Normally, no matter how angry I am, I just stand there and fume silently. However . . .
GTA:San Andreas - whoever had the brilliant idea to stick the "Red Baron" mission in there BEFORE you learn how to fly (not that it even matters, that RC plane handles like a pregnant whale) should be drawn and quartered! It took me at LEAST 15 tries, no joke. This little incident cost me a controller.
God of War - Playing through on Spartan (or whatever the Normal equivalent is)took all of a week. I got to the end boss battle with Ares and thought "this is IT!" Unfortunately, my PS2, being an older model, couldn't handle it when the combatants got in the little shoving match they have. Actually, that's not true. Whenever Ares won that little sparring match, the game worked fine. Whenever I won, the console froze up as solid as a block of stone. Oh wait, I forgot, it also looped the sounds of Kratos and Ares's manly grunting (read: it sounded like two men making sweet, greek love). This little incident almost cost me a friend, as my roommate thought the situation was HILARIOUS, and I decided to yell at him about that for a few minutes.
