First of all the auto kick function some games (cough cough Halo) has annoys the living hell out of me.
Then you get the games where people litteraly do not shut up and go on and on about every little thing or plan or idea they have in the middle of a fight.
Lastly, this one amazingly enough is not a multiplayer or online peeve, no this is when game developers come up with either pointless boss fights that are purposely stretched out with the use of a cutscene, have a regenerating health bar by the end of it or are just simply a multi tiered boss battle with no actual difference in attack style and or difficulty per tier, its just plain laziness.
