From my bad memory, the most frustrating game(s) would have to be Call of Duty.. any of them. It's just the fact that I'm playing with the RL people, and for some reason every time I get killed, I think "that person's a jerk!". I always have something to complain about: like someone's camping, or someone's noob tubing, or the fact that I hate how shotguns are everywhere, lag, people talking trash, and waaayy more.
Whereas I hardly rage at offline games, because my mind tells me it's my fault for losing/dying/etc. Like if I can't beat this boss, that means my strategy isn't good enough, or I should grind my levels, and I usually end up quitting before I rage anyway.
So only online multiplayer games get to me, really :-(
