I think we had a topic like this before, but I don't really feel like actually looking for it so why not make a new one. Despite how awesome video games can be (well the good ones) there's always something annoying thrown in by the developers or something you just think is stupid.

--accidentally selecting "yes" when a NPC asks you if you want his ten minute speech about how to move with the analog stick repeated
--no save points between a ridiculously hard dungeon and its boss
--no save points between a ridiculously long cutscene and the ridiculously hard boss that follows
--thousands of ammo clips and no health packs when you need 'em
--games that have stylish moves and combos, but are way less effective than simple button mashing
--checkpoints where you don't need them
--no checkpoints where you do need them
--backtracking to and fro for a meaningless task (exception: Metroid Prime games handle that well)
--stealth games where you want to be sneaky but you get frustrated and blow everything to pieces (y helo thar Hitman games)
--most water levels
--escort missions, I wish I could meet escort missions in real life so I could punch him in the face
--timed escort missions, escort mission's inbred cousin
--when you have to go around a small obstacle like a fence or a one-foot wall and travel past ten minutes of area to get to the other side
--timed puzzles
--rubber-band/changing difficulty throughout the course of a game

Also, more games should have a new game+ option, but that's a different topic.

Yeah, I think I'm done for now. Share your annoyances.
