"I didn't exactly mean to do this, but I had a vampire couple that had triplets. They couldn't get up during the day to take care of the babies because they would burn up and start to die, even though I put no windows on the house. They were also really poor so they couldn't hire a nanny. So the babies would cry, the vampires would wake up and try to take care of them quickly, then go back to their coffins. But the babies cried so much that eventually both parents died and the social worker took the kids away. Not a good experience for anyone involved."
"One of my Sims had the desire to sleep with ten people. She had a husband who was an artist. He was always in his studio endlessly painting, he had a bed in there, he was completely dedicated. Every time she had a lover over I had him paint the scene in the bedroom. He never caught her as he rarely left his studio but all the time he was obliviously painting her infidelity. Obviously I hung these paintings all over the house."
"Giant two story maze, room in the middle of the bottom floor had a fridge and the one up top had a toilet. It took 48 sim hours to get through the maze"
"I made a Black Widow, a female sim who would marry men and on the wedding day I would lock him up in the basement and basically starve him. Her secret cemetery/basement had like twenty urns. I didn't even do it for the money (I would donate it all away, she had the 'good' trait so it would actually benefit her too). I never had her have sex with any of them either, she died a virgin after adopting a baby girl and then I repeated the entire cycle with her as well."
"Killing Sims is (generally) too easy and vastly overdone. So one day I was an a mischievous mood so I decided to perform a "social experiment". I built a very bland house. Basically a big square of unpainted walls without windows and only 1 door. Once I had the whole neighborhood trapped inside I remove the only way out. Inside the house there was one refrigerator (no starving to death allowed) and, right in the center of the house, a single toilet. I wanted to see which Sims would unashamedly use the toilet in full view of everyone else. Most did not want to. Slowly I would shrink the walls as people moved away from them forcing everyone closer and closer to that one, lone toilet. The whole neighborhood, all fed and needing to use the toilet, nearly all too ashamed to user it standing around in a tight, confined space all staring at the toilet longingly. Many were standing in puddles. Woe betide them that fainted. Mwuhahaha."
"He was tired so I made him drink coffee over and over cup after cup he pissed himself constantly, cried and became depressed until he dropped dead leaving his baby orphaned to die alone in her crib."
"I made a town where everyone was a female clone of this one guy, moved that guy in, and had him slowly move his way through impregnating every one of his clones."
"I would make a kid be a really good painter and then force them to paint the parents woohooing. I would invite everyone in town over and then turn the house into a pool with no ladders so everyone would drown. Once I trapped Death in a wall."
"Every time I play the Sims, I start my family with a painting goblin. I make him/her morbidly obese with green skin. I make sure he/she has the following traits: likes to be alone, likes art, hates the outdoors. The first thing I do once I have enough money is build a small green room in the basement, send him down there, and then remove the stairs. I set up a tiny little area with only an easel, a toilet, a fridge, a bed, a shower and a trash bin. All he does all day is paint. He paints and paints and paints and paints. Eventually his paintings become very good and worth a lot of money. Every few minutes I go downstairs and sell whatever painting he has finished, and then I return to playing the game. My family always ends up feeling blessed because of their fortune, and they never find out about the horrible secret living beneath their home."
"Married a female sim to kill her so her husband would be single. She was pregnant. Let her have the baby. Locked her in the basement. Married her husband. Raised the kid. She died when the baby grew into a toddler, same day as the party. Nobody noticed."
"I bought a giant mansion but made some modifications to it. By modifications I mean a room called "The Party Room". The party room had dance floors, plenty of food, music and a nice sports car parked in the middle. What could go wrong? I threw a party and invited everyone I knew into it and called them into the room. Suddenly the doors shut and a nightmarish hell began. All the stereos switched to that annoying kids music, the strobe lighting kicked in and the fireplaces lwere placed. The doors disappeared magically. The sims weren't allowed to leave the house. I had but three commandments: Anyone who does not dance dies, anyone who tries to put out the fires dies and the last surviving member was allowed to live. At least 30 sims had to endure fire, starvation, piss covered floors, strobe lighting, kids music, windows that pointed directly outside to freedom, ghosts and rotten food for about two weeks ingame. One by one the sims were picked off through horrific torture. At last there was a lone survivor- an old woman. I placed down a door and allowed her to leave. I made her walk down a long corridor with large windows showing the devastation in the party room. I then gave the house to her and made her wear only black. That's not all, even after this I made her invite anyone that walked past the house into the house and lured them into the party room. Eventually, I made her call the police and pretended that they shot her by dragging down her hunger meter using cheats."
"Was obviously a bit gay. Did not realise this at the time, but my Sims games should have been a dead giveaway. Lesbians everywhere. All lesbians. Lesbians with kids, 'best friends' living together, super hot female celebrities woohoo-ing it up by the waterslide, entire town was a veritable lesbian paradise. Except for one guy. Imagine this: you're a perfectly attractive young man who moves to the centre of Clungeville, but because your malevolent Sapphic creator is working out her issues all pussy is off-limits. I'm sorry, Greg. I'm so sorry."
"I once set up a Sim to have my exact life. The Sim spent all the time crying. :-/ I stopped playing after that."
