Name some humorously sick or ridiculously cruel things you've done in videogames. Preferably not a scripted event (i.e, MW2 Airport scene doesn't count)

For me... well, probably the time in Fallout 3 where I massacred a bunch of raiders in a house, then cut their bodies apart with the ripper and spread them around the house. I believe I put one person's head in the toilet.

I was bored -__-

I played Postal 2.

'nuf said.

In Conkers Bad Fur Day (N64 Version) i used to play the multiplayer a lot (With bots) and i used to love blowing up and generally killing my teammates with grenades,rocket launchers, throwing knives and samurai swords then after killing about 3 allys they would turn on me, i used to ROFL all the time at it and spend hours playing the game. It was so fun but it affects me in todays mulitplayer games since in some of them if i get bored i usually team kill for Lolz reactions from people. It's turned me into a video game troll.

Does forcing Zaalbar to kill Mission in Star Wars: Knights of the Old Republic count?

This, and did the same thing to the children using a mod. This.

Spent an hour on GTA4 making a giant car bomb and detonating it by a mall-like area.

My entire playthrough of The Sims 3.

I'm bookmarking this topic! :D

Just Cause 2:
Attaching some poor guy with my grapling hook to my car, dragging him behind it and then driving off a cliff. If they survived and there was a boat nearby, I'd attach them to the boat and continue the fun. One of them tried to pretend he was dead (his limbs/head were all hanging down in the water) but as soon as I attached his "dead" body to a boat he started crying for help again.

I once created an adventurer in Dwarf Fortress with maxed out skills in close combat and went about tearing off the extremities of innocent peasants with bite attacks using the then-new aim system

I have seen some other adventure mode stories, however, that made that whole incident seem pretty tame

this, also used cheats so could fire unlimited amounts of cats (also used as a silencer) and most people would start puking after getting hit by a cat so sometimes there might be 5 or 6 people in screen puking around...

edit:
added few screenshots, nsfw so look at your own risk

This will make most of you guys hate me...I played Postal 2 and whoever played it KNOWS that you can seperate head from body by shovel...and head looks like what? A ball... so I had huge collection of these balls, I kicked them around, kicked them at people, kicked them in policeman face....good times, good times :D

- Killed the annoying pickpocketing children in Fallout 2.
- One of my old WoW characters was female, and some fellow thought that meant that I was too. I didn't say anything, and apparently he continued to think so for nearly a year of constant questing, etc... Eventually, he started to make advances, and I informed him as to my gender. He was pretty broken up, actually. Can't say I remember seeing him play the game again.

Postal 2.
1. Collect heads.
2. Set on fire.
3. Kick flaming heads at crowd.
4. Laugh really hard.

Hitting the dinosaurs in Star Fox: Dinosaur Planet with your stick was awesome.

I don't really do this kind of stuff. It honestly kind of weirds me out that some people do, but I'm not judging.

Ultima VII: Killed everyone in Trinsic in Ultima VII, i then moved all the bodies to the church. I did it a few times.. Actually, i still do.

Blood: Kicked a lot of heads through various openings.

Minecraft: I'm currently purifying Minecraft of the horrendous idea ot Notch, called the Mushroom biome, and the abominations that inherit that place, by planting TNT and creating fenced areas filled with ignited netherrack, using it as a grill for the 'mooshroom' cows. I sometimes use the fishing rod to propel the cows into air, and let them fall to their deaths or into the fire. I then purify the land with the aforementioned TNT.

Oh, less cruel thing in Deus Ex: Human Revolution: taking down pedestrians who weren't nice to me.

[and yeah, these aren't really that random]
