-i agree with stompy(alike most others) i hate timed ANYTHING in games such as the epilog on cod4 (only during veteren mode...ITS PISSIN MEH OFF!!)
-when the game developers continue to change the release date on games (im looking at Spore which is looking EPIC but i have been waiting for, for about 3-4 years now)
-mic spam (especially when it is little kids)
-games that look like they r gonna b awsome then end up horrible
-tkers (team killers for all the noobs out there)
-hackers/cheaters/autoers/etc.
-dumb teamates (ai and multiplayer)
-people that make up dumb excuses 2 y they couldnt kill u ("oh i was scraching my nose" or "i dropped my controller)
-trash talkers (when people act all big and bad.but i do love it when u completely pwn them)
uhh i cant think of anything else at the moment so yea...
