Torchlight because I know wen I play my items will pwn all the enemies

Slender

Minecraft. Just mining the stone in a straight line

Team Fortress 2

Killing Floor for all occasions.

L4D2 on Easy with Chainsaw Massacre mutation.

Binding of Isaac, because the game is so simple and yet demands great concentration.

Cleverbot

Toontown.

I don't get angry lately... but the game I like the most to spam grenades and hell, it's Saints Row 3.

Usually multiplayer games make me rage rather than the opposite

Prototype and GTA:SA

I go outside, take the mace and break stuff, or take the axe and cut some wood, easy. Otherwise could be puzzle games like Lumines or massacre games like Orcs Must Die.

The drinking game.

Left 4 Dead 2 with the Gib Fest mutation.

NFS

Team Fortress 2 I either end up with more anger or less, but in the end it was a good day

Action/Adventure games.

TF2 and/or Dota 2. There is the chance that I get angier because of those games but the point is to take my mind off whatever I was thinking of which usually works.

QWOP

Boxing on Wii Sports =P

trials evolution or halo reach

I know i'll be bashed for this, but I play MW3 to vent. Its like passing the Olympic rage torch to someone else.

Saints row 3 on zombie mode. Unfortunately, I sold it. So now I bottle up my anger, and It slowly grows, one day culminating in an explosion so large it will destroy the very universe. God save our souls.

Moral of the story: Always make sure you have a copy of Saints Row 3 on-hand.
