TF2,

Farming Simulator 2011.

It helps me gather my inner chi and awaken my zen.

Killing floor, heads will explode

Postal 2, Duke3D...

Grand Theft Auto IV
there is no more fun thing to do than killing hookers when u had a bad day

Currently? Wargame: European Escalation. It takes enough focus that I lose sight of whatever's been frustrating me.

When I'm really frustrated I play Super Meat Boy, otherwise it's a mix between GTA Vice City and We<3Katamari. There's nothing like taking your anger out on unsuspecting video game characters.

any sort of strategy game or ones that involve massive killing sprees :)

i play garrys mod :D

trash keyboard

Europa Universalis 3

Grand Theft Auto: San Andreas with awesome cheats on like super punch and infinite ammo with the minigun.

Sex.

Hello Kitty Adventurer Island

Spore, it's simple and calming.

WH40K-related games. :) They are also good for when you just want to play something. ;)

Warhammer 40k: Space Marine.
Serious. Munch through a few Orcs' guts with a chainsword/power-axe or crush a few Ard-Boyz' heads under their shields and you'll feel a (metric) fuck-tonne better.

For me, it's youtube. I start to hate the popular youtubers :D
