We play EA’s Sims 4 to experience a detailed simulation of human life.
It’s fun to watch the wacky situations our sim counterparts get themselves into… or the situations we force onto them for our amusement.
But The Sims contrasts substantially with human life in its cartoonish nature. Everything is funny, absurd, and sims just take everything as lightly as possible. For them, life is simple.
Well not anymore! Thanks to the tireless work of some amazing modders, we can re-introduce some of the more nuanced aspects of human life into the game, increasing the simulation’s complexity and often making everything just a little bit darker, grittier… more real.
For anyone interested in making their Sims experience as real as it can be, here are the some awesome mods for increased realism.
20. Realistic Reactions
Have you ever been cheated on?
Hopefully not, but let me tell you it isn’t chill.
For this reason I always found it unrealistic that sims would just get angry at their cheating spouse for a little bit before returning to normal, at least whenever infidelity was actually discovered.
Creator Scaldwellhu agrees. And they made a mod to make cheating as big a deal as it usually is in real life.
Now couples will be devastated by the event, and it’ll take a lot of work to get things back in order. Even the kids will feel upset when their parents are in this situation!
19. Miscarriage Chance
Pregnancy is a beautiful process. But sometimes there are complications, and that’s just a fact of life.
This mod by LittleMsSam introduces a slight chance that one morning, a pregnant Sim may wake up with cramps and abdominal pain, prompting them to go to the hospital.
While sometimes they’ll come back with a healthy baby and make everyone in the household relieved, more often than not they’ll return with dark news despite the doctor’s best efforts.
It’s sad, it’s dark, and it’s incredibly realistic.
Now on the flip side, if you want pregnancy custom content that’s a bit more light-hearted take a peek at our pregnancy mods list. Not as much realism, but a whole lotta fun in there.
18. Pregnancy Overhaul Mod
Creator LittleMsSam doesn’t just want to put a damper on your reproductive fun.
She just strives for realism, which we can find in her Pregnancy Overhaul Mod.
Not only does it replace the absurd pregnant belly size found in vanilla for something more anatomically correct, but it removes the exaggerated pregnant walking animation as well.
It also lets expecting sims continue practicing yoga, swimming, and other such activities up to the beginning of their third trimester, as is normal for would-be-moms in real life(which I had to Google to confirm, I mean I’ve never been pregnant so…)
17. Risky Woohoo & Try For Baby Chances
Normally you can actively choose whether you want a sim to have safe Woohoo with a partner, or outright try for a baby and get them pregnant.
But that’s not quite how it works in real life.
Modder PolarBearSims came up with some tweaks to make the Woohoo experience more immersive by replacing it with Risky Woohoo, and implementing a complex fertility system affecting all sims.
Depending on their fertility levels, location of the encounter, and some other factors, some sims will have more of a chance of becoming pregnant accidentally than others. Sims may also become infertile, requiring them to get fertility treatments to actually get pregnant. If that isn’t real, I don’t know what is.
16. More Best Friends
I’ve never been able to give a definitive answer when someone asks who my best friend is.
I would never be able to pick just one. They’re all key parts of my life!
Thanks to creator LittleMsSam, your sims won’t have to pick just one either.
Now the “become best friends” interaction will have a 30-minute cooldown rather than a one-time use, allowing you to create inseparable squads of Sim besties.
15. SNB – Sim National Bank
The way money and bills work in The Sims 4 is pretty basic for a game made for simulating human life.
Sim National Bank by SimRealist is an in-depth mod that endeavors to overhaul the financial system in TS4, letting sims manage bank accounts, take out loans, pay their bills individually, and so on.
Quite honestly, this is one of the most realism-enhancing mods I’ve ever seen.
But only the most hardcore players will actually have fun introducing accounting into their sim lives, which is why I don’t place it higher in this ranking.
But let it be known, this mod is exceptionally realistic.
14. Personality Please!
Sims are notoriously less complicated than humans. They take life one day at a time and often choose what feels right in the moment, rather than what makes sense in the long run.
Personality Please! by PolarBearSims is a mostly romance-centric rework that makes Sims considerably less promiscuous by making traits, aspirations, and past events greatly affect their relationships with other sims.
Now they’ll actually need to be compatible if you want them to get down and dirty.
Other than that, the mod also gives cats and dogs more varied personalities, and sims can learn traits and choose careers just from having deep conversations with others. How cool!
13. Automatic Beards
Ever since I turned 14 years old, my ever-growing beard has been an important part of my life.
Every morning I decide whether or not to shave, and the choice has important ramifications on how my life plays out. The same should be true of our digital friends.
This mod makes sim beards grow automatically over time, requiring constant shaving. Unless you want your sim to become Gandalf the Grey, that is.
12. SimDa Dating App
Dating and finding partners is astoundingly easy in Sims 4 compared to real life. Which is why we needed dating apps, and they don’t – until now.
The SimDa Dating App by LittleMsSam works a lot like a streamlined version of Tinder, allowing your sims to schedule meetings, set up blind dates, or simply call somebody over for a one night stand.
Each of these interactions has its own interesting features and possibilities.
You can start relationships, have some fun… and even get someone pregnant by accident. Just like real life!
11. The Explore Mod
While there’s a lot of places to visit and activities to enjoy in The Sims 4, there’s always room for some improvement.
And more autonomy is always good.
The Explore Mod by KawaiiStacie lets your Sims go out and explore the world autonomously, either alone or with friends.
They’ll have adventures, gain skills, meet people, and maybe even change their world view!
This mod adds several entertaining activities like gambling, getting your nails done, doing temporary work for an extra buck, and even going out to get takeout if you’re too lazy to cook. All very realistic and very immersive.
10. Height Slider
One of the most frustrating and unrealistic things in the game is how every sim is exactly the same height as others of the same age group.
Well thanks to this mod by creator Luumia, you’ll be able to give your sims different heights through a slider in CAS.
Everything else will, of course, scale proportionately to height.
As a bonus, Luumia included a hip shape slider and neck length variation for even more Sim variety.
9. Extreme Violence
The world is a very violent place, and even peaceful suburban areas like see their fair share of violence from time to time.
Extreme Violence by Sacrificial Mods adds the possibility for wrongdoing sims to attack others in a wide variety of ways.
Shooting them with machine guns, cracking their necks, chopping them up with a machete, and even crushing their skulls by sitting on them are only some examples.
I mean, I guess it’s realistic?
Not only does it add the acts in themselves, but a bunch of added functionality revolving around them, like the possibility for sims to acquire the Serial Killer trait, or paying a gang to off someone your Sim doesn’t like. Yikes!
8. Meaningful Stories
Sims don’t take life too seriously, and they’re incredibly fickle.
They may be completely devastated by the death of their pet one moment, then ecstatic because they watched a good movie the next with no in-between.
This mod by Roburky reworks the mood and emotion systems to make them more nuanced and realistic.
A depressed sim will need time and help from their friends to get out of a rut, and something like a first kiss will make them feel happy like never before.
Transitions between emotions also take time, and there are transitional periods when they’re feeling a bit of everything.
7. Passionate Romance
The romance system in vanilla TS4 is pretty basic.
You can flirt, go on dates, Woohoo and get married, but it never really feels like a relationship.
Passionate Romance by Sacrificial Mods improved this greatly by adding several new interactions like snuggling, hugging romantically, taking a romantic selfie, and even grabbing each other’s butts like they used to in TS2.
6. After School Activities
Going to school has never been just about learning history or science.
It’s also about making friends, acquiring skills, and finding yourself.
With this add-on by amazing creator KawaiiStacie you can add all these things. It endeavors to flesh-out educational experiences by adding over 30 after-school programs for children and teens.
Examples include the Anime Club, the Yoga Club, band, and basketball.
Sims partaking in these activities will learn skills, make friends, gain motives, and may even apply for scholarships depending on their performance throughout their school life.
5. Wicked Whims (NSFW)
If there’s something humans never get tired of, it’s sex. We love it, and so should our Sims if we’re to have a realistic experience in-game.
Wicked Whims goes a long way to develop everything sex-related in TS4, from turning the Woohoo interaction incredibly graphic to giving female Sims a fully-functional menstrual cycle complete with mood swings, cramps, varying fertility and a need for pads and tampons.
This one goes deep.
It even introduces contagious STDs! Now if that isn’t seriously realistic, I really don’t know what is.
4. Basemental Drugs
Alcohol and other drugs have been a reality of life since time immemorial, and that’s not about to change anytime soon.
Basemental Drugs endeavors to introduce this reality of human life into TS4. It lets your sim pals acquire, consume, and sell alcohol, tobacco, cannabis, and many other mind-altering substances.
Sims engaging in these activities may become addicted, have problems with the law, get arrested, and even go to rehab… and that’s only the tip of the iceberg.
It’s not pretty, but it is the real world.
3. Basemental Gangs
If you like Basemental Drugs, the Basemental Gangs expansion is sure to pique your interest.
It fleshes out the entire drug dealing aspect of the mod, allowing you to create a criminal empire and become the leader of one of four gangs.
Again, dark but quite brutally realistic.
You’ll have underlings, earn loads of blood money, and there’s even an entire skill system to become a better thug. It may not be wholesome, but it sure as hell is realistic.
If you’ve ever wanted a little more GTA in your Sims experience, this mod is the ultimate crossover.
2. Life’s Tragedies
As you may have realized by now, not everything is glitter and candy.
There are tragic and difficult moments in everyone’s lives. And they can arrive when you least expect them.
Life’s Tragedies by Sacrificial Mods adds a wide variety of possible tragedies that may befall your Sim or NPCs close to them. Like randomly being run over by a car, getting jumped by a homicidal maniac, or even contracting a life-threatening disease they’ll need surgery to overcome.
It may seem a bit intense, but don’t worry. You can control how often these tragedies happen, so you can either turn your Sim’s life into a horror story or just inject a tiny bit of dark realism into your game.
This will be absolutely hilarious, devastatingly upsetting, or some kind of in-between, depending what you’re looking for.
Just note the download page includes a lot of other mods from this creator, so look towards the lower part of the screen for their “Life’s Tragedies” download file. It does get updated from time-to-time so if you want the absolute newest version definitely grab it from the link above.
1. Slice of Life
Easily the most comprehensive and complete realism overhaul for The Sims 4 is Slice of Life by KawaiiStacie.
It’s an extensive mod that touches almost every aspect of life in the game.
Your sims get visible emotions, recurring memories of past events that’ll affect their moods, a complex fitness system, and reactions to their own appearance. Among many other things!
One of the most impressive features of the mod is giving every single sim a personality based on the Myers-Briggs 16 personalities test, which affects the way they behave and interact with other sims to a great extent.
It also adds many features we’ve already seen in previous mods such as functional alcohol, serious sickness, and a complex menstrual cycle, all in a single polished CC pack affecting every sim in your world, including NPCs.
This is truly the ultimate realism mod for The Sims 4, hands down.
If you need a one-stop shop realism mod then give this a try before anything else. You’ll be surprised how much it offers.

Vampires have been part of our collective for hundreds of years, at least in one way or another.
And considering just how popular they are nowadays (thanks Twilight) it’s no surprise they also found their way into The Sims 4.
The Vampire Game Pack was released way back in 2017 which added vampirism, vampire powers, and a new residential world called Forgotten Hollow where these creatures of the dark prefer to live their “lives”.
It was a massive content update with new aspirations, traits, and a lot of CAS additions. And yet, people still don’t have enough.
New vampire CC is still some of the most requested by players. And modders work tirelessly to deliver.
If you’re one of those people that just can’t get enough of the mysterious bloodsucking creatures, well then this gallery is for you.
17. Vampire Sun Immunity
Do you know what sets vampires from Sims 4 and Twilight apart?
TS4 vampires wither and die within seconds of being under the sun, while those in Twilight just… sparkle.
Well this mod by creator RevyRei won’t make your vampires sparkle.
But it will make them immune to the sun’s UV rays.
Now your trendy Millenial nosferatu can freely enjoy the beach, picnics in the park, and going to Coachella with the squad without worrying about the Reaper visiting them.
16. Vampires – Free Perks
Another somewhat cheaty but useful addition to your Sims 4 mod library is this freebie by modder Baibaihe.
As you probably got from the name, this simply makes all vampire perks free so you won’t need to spend any points to become the best vampire that ever was.
It’s ideal both for outright cheating, or just softening the difficulties of vampirism by getting stuff like Tamed Thirst so you don’t need to kill.
Alternatively there’s a toned-down version that only makes the perks cheaper, to streamline your vampire’s progression without outright removing it. So it’s not totally game-breaking that way.
15. Vampires – No Weakness
And why stop at making perks free? Why not also remove any downsides to vampirism?
Both of these mods are just meant to let you play around freely without worries or limitations.
After all, didn’t your Sim become an immortal being to have fun?
Or you can also choose to make a Sim with every single weakness, a wretched being full of hatred and frustration! Why?
I don’t really know.
But what matters is that you can.
14. Slower Thirst Decay
Have you ever felt like your vampires are a bit on the greedy side?
Just a couple of neck sips a week should be enough to keep them going… and yet, they seem to want to drink the whole neighborhood.
With this small tweak by modder Baibaihe your vampire’s thirst motive will decay half as fast. So you don’t have to worry about having to risk your life hunting in the middle of the day.
I mean sure, you could make some plasma packs. But who wants to hunt that many frogs?
13. Turn Into Vampire Always Succeeds
Another minor inconvenience that vampire Sims may run into from time to time is wanting to turn someone into a vampire and failing in the process.
Especially during the day.
Thanks to this simple tweak by modder Couch, trying to turn another Sim into a denizen of the night will never fail. This actually lets you turn everyone in your town into your blood-bound slave, if you desire.
12. Plasma Pack from Plasma Fruit
One of the few ways for a vampire to avoid having to feed off another Sim is to make Plasma Packs by processing frogs or fish into bootleg blood bags.
But isn’t that a bit unfair towards them?
Prolific creator LittleMsSam certainly thinks so.
Which is why she made this simple mod that lets you take Plasma Fruit and turn it into Plasma Packs rather than eat it directly.
They’re 50% better at quenching your thirst, surpassing even homemade Plasma Packs made out of the previously mentioned critters.
This is ideal for Sims with the Good Vampire aspiration.
11. Vampires: Stop Pestering Me!
One of the first things you’ll notice after installing the Vampires Game Pack and meeting some bloodsuckers is that they’re very insistent on trying to consume you at inconvenient times.
They’ll make creepy calls, invite you to sketchy places, and even break into your home to try and suck you dry every other day.
Long story short, they can be unbearable for the average sim.
Now thanks to this mod by Vwaryloth you can rest easy knowing vampires can’t invade your home. They’ll also stop being creepy towards you, and Vlad will simply leave you alone.
10. Harvestable Heart Tree
I love trees that grow things that aren’t fruit.
The trees that grow money in Animal Crossing: New Horizons are a prime example. And now, so are Vampire Heart Trees in TS4.
This mod by IceMunMun was meant to serve as a sort of Valentine’s Day celebration for vampires, introducing edible Vampire Hearts that fill their thirst.
And it can even be used to cook vampire food given the recipe uses fruits.
These hearts grow from a very special tree that you can plant and nurture yourself, and it may grow different kinds of heart fruit that not only glows different colors, but will give you moodlets like Flirty or Happy.
It just adds to the fun, really.
9. Airianna’s Vampire Tweaks
There are a couple things about vampire gameplay that simply make no sense.
Things like always being out of vampire energy, and the fact that several traits related to hunger or energy do not affect them.
Thanks to these Vampire Tweaks by modder Airianna, Vampires will now use Dark Meditation to replenish their Vampire Energy whenever they’re idle.
And some traits like Hardly Hungry and Never Weary have been modified to affect Thirst and Vampire Energy in the same way they do normal sims.
They’re small changes, I’ll admit.
But after a few hours with this mod you won’t be able to go back.
8. Vampire Powers
Instead of simply installing a mod that cheats your way out of avoiding the sun or having to drink human blood, consider this immersive alternative by modder LittleMsSam.
The way this mod works is adding a couple of extra powers your vampires can spend their vampire energy on, including enabling their mirror reflection, stopping uncontrollable hissing, and becoming immune to sunlight.
These effects are temporary and will fade away after seven in-game days. So they’re perfect for those times when you just wish your sim could attend a specific daylight event.
7. KM Vampire Eyes
If you’re just looking for a bit more variety in your vampire Sims’ looks, KM Vampire Eyes is something you can’t pass up.
This mod by creator KittyMeow adds 10 new eye colors and some variations, available for all sims if you’d like, but intended to be used on vampires.
Among the most unique are a couple that turn the sclera (the white of the eye) completely black, which creates a great contrast with bright iris colors.
6. Vampirify – Vampire Creation Spell
In a world where vampires are real, learning the most you can about them is a matter of life and death.
And this is something that anyone well-versed in the magical arts should be keenly aware of.
With this mod by R3M, studying so much vampire lore will eventually give spellcasters the Vampirify spell. Which not only turns anyone into a vampire, but makes whoever cast the spell into their master.
All of this despite not being bloodsuckers themselves. Dark, yeah?
As a bonus they’ll also gain a spell to reverse vampirism and turn denizens of the night back into normal humans, which is an invaluable skill for anyone living close to a vampire den.
5. Vampires Can Kill
Despite being named “Vampires Can Kill”, this mod by Zer0 is actually a collection of vampire-related tweaks that go beyond whether drinking blood can end a life.
Its primary feature is, of course, adding the possibility to kill other sims by over-drinking. Whether on purpose or by accident.
For some of you I know it’s no accident. Remember all those years of removing the ladder out of the swimming pool?
But by far the most interesting addition from this mod is turning all sims into cattle through the Manipulate Life Spirit interaction, binding them to the vampire in a sort of symbiotic relationship.
Cattle Sims are only happy when they’re serving their master. But will slowly wither away and die as the vampire sucks them dry, bringing their story to a tragic end. How fun, yet tragic. Yet fun!
4. Immersive Vampires
Another amazing mod by vampire-lover and modder Zer0 is Immersive Vampires.
This makes living as a vampire sim not only more realistic, but overall more engaging.
It fleshes-out vampire gameplay by giving you the possibility to confess your vampirisim to other Sims, either to scare them or because they’re your friends and you just want them to know.
However not all Sims will react the same. And they all have their own opinions on vampirekind based on their traits and past experiences.
You can try to convince them vampires aren’t that bad, but you won’t always succeed. And some might even become vampire hunters and make it their life’s mission to unmask you and your kind.
3. Event: Vampire Initiation Ritual
Willingly becoming a vampire is something that does not always get treated with severity.
You’re becoming an immortal. That’s got to be at least as important as a wedding!
Polish creator IlkaVelle took it upon herself to make an event out of it, complete with a Senior Vampire host and both vampire and human guests.
If you manage to pull off a good turning party you’ll get a sizable starter pack including Plasma Packs, Plasma Fruits, the Ultimate Vampire Tome and even a Coffin so you can sleep in peace. How sweet.
2. Darkside Vampire Career
Rumors have been circulating all around town about the Darkside Club.
This is a new nightclub with a secret… it’s actually a hub for vampire operations and entertainment.
This mod by TiaraM opens the doors to three different career paths, all beginning at the Darkside.
Whether you want to become the vampires’ plaything, turn into a denizen of the night yourself, or devote your life to hunt them – it’s up to you.
Serial Killer Mods Sims 4
Personally, I think becoming a premium escort for vampires and getting paid to let them suck my blood sounds like a dream job. Better than McDonald’s, at least.
1. Bloodborne Aspiration
Based on Vampires “Don’t Sleep Alone: Your Guide to Meeting, Dating, and Seducing a Vampire” by Elizabeth Barrial, this mod by creator Sresla introduces a new aspiration for vampire sims bent on discovering the truth about their ancestry.
And it’s a doozy.
You’ll go through several stages, learning about vampires and completing tasks that little by little reveal the truth about your Vampiric Caste.
If you’re looking for something to give your adventures a bit of narrative structure, the Bloodborne aspiration might be your ticket to hours of fun.
