A little background: I'm an only child that was shuttled from my single dad to my uncle and his partner Uncle Phil. My uncle is my best friend, only 13 years older than me, and since he and his partner don't have kids of their own, I'm pretty much their kid.
Until he got Sims.
We had a grand old time at first. We both had our own individual games and I played as myself with my uncle and Uncle Phil as my neighbours. My uncle had a similar set up with him and Uncle Phil living together but they also made a baby Sim me (so there were two me's technically but that's not important). Basically my dad Sim got a chick pregnant and he killed the chick after I was born (this does not reflect my actual past), and then sent me to live with my uncles and then we killed my dad (also does not reflect past). So I was living with my uncles and everything was fantastic. I grew to become a strapping young sim who was looking forward to a career as a chef.
So in real life, I was sent back to my dads for a few months. I didn't have Sims there so the game drifted into the backgrounds of my life. Occasionally I'd ask my uncle how his game was and he said it was doing great. That was all on the subject.
Then I went back to my uncles, and the next day once I was all settled in and my uncles at work, I went on the computer to check out how the game was going. Out of curiosity, I clicked on my uncle's game to see how sim me was doing.
I wasn't there! And not only that... my uncle and Uncle Phil had FOUR OTHER CHILDREN NOW! They had a stupid baby, two stupid children, and a stupid teenager sim. They all lived in a big house and were all quite happy with each other and I was nowhere to be found.
Angry, I went to the neighbour hood screen to find me... and where was I? I was in a small shitty little shack that was missing a god damn roof! I also didn't even have a damn toilet or a bathroom, just a telephone so my selfish fuck uncle could still call me to hang out so he could have me as a friend. I was just sitting on my shitty small couch watching my bullshit crappy television surrounded in my own god damn filth.
This... obviously... was unacceptable.
So what did I do? I went back to my uncle's game with his stupid happy family. I bought a fireplace and got Uncle Phil to light it, then told one of the kids to go and check it out. I surrounded her with cheap chairs, and watched with delight as the chairs lit on fire and she burned to death in front of her screaming parents. Then I locked the other child in what I affectionately called 'the death room' and took away the door so he could slowly starve and eventually die soaked in his own piss. While he was dying, I forced the teenager to work out on the gym until he was exhausted, and then I told him to go for a swim and did the classic 'remove the ladder trick'. Then I moved the baby to the edge of the screen and let the little bastard cry and stink far far away. Unfortunately for the kid locked in the death room, this came too late, he died before the social worker could find a way in to get him (which there was none, so perhaps it would've been useless).
Then I moved my sim back in to the house, where he belonged.
Oh and their urns and the tombstone? I took their urns and put them on the shelf by the fireplace, and the tombstone by my uncles' bedroom window.
Just as a warning for them to never do such a thing again.
After I did all of this, I closed the game and carried on as usual. It wasn't until about two or three days later that my uncle walked into my bedroom with a flat look on his face and told me simply but firmly I was a psychopath. And I reminded him simply but firmly, that we were a one child family, and it would be best that he never adopts any children.
