In truth I cannot remember really getting mad at the game. I get mad at the people playing the game.... and cheating. I.E. Halo Modders. Are you so hard up to be better than everybody that you have to hack your system/game and look like a complete douche? I used to enjoy online FPS, not anymore. Not saying I myself don't cheat, but I don't cheat and screw someone else over.
As for venting, it used to be any other game that allowed me to cause ridiculous carnage/destruction and laugh at the results. Now... it's sex with my Fiance' lol, or both. Not at the same time or in that order.
Obey the law! Wheatons law! "Don't be a dick!"
