1)The CPU or anyone on Xbox Live, constantly using the same move on Soul Calibur 4 or any other fighting game, which picks you up of the ground, hurts you and drops you down again repeatedly.
2)Falling through graphics on games, like WoW, or getting stuck in the graphics, for example in gears of War.
3)In any game which has a driving sequence, and you can have an AI controlling the vehicle, while your controlling the turret and drives stright into fire by the enemy.
4) On Persona 3, the enemy uses either Mudo or Hama(or the higher level versions), gets lucky, the main characters dies(You get a gameover if the main character dies... :|) and game over and then having to start back 10floors below..... (Shortly after that i found out the best way to avoid losing floor progress is to run to the next save point floor, and then go back down and go up normally to level up... :x)
5) On FPS' when your hidden behind something, really far away and the enemies seem to have super vision and extra long range fire and managed to kill you from a mile or 2 away.. :Z
5) On a platformer, the camera angle suddenly switches and you end up jumping off the cliff instead of up the step or whatever. :X
I could think of more, but i'll refrain.
