1: In FPS games, I show a single hair of anything on my body, and every enemy soldier, sniper, tank, bomb, grenade, and anything potentially fatal is suddenly pointed at me (looking at you, CoD)
2: When you are supposed to go somewhere, but for the life of you, you can't figure out where the gently caress it is.
3: When your stupid allied AI walks right into your line of fire and gets shot...then you are told that "friendly fire is not tolerated" Yep, mission failure.
4: Psychic enemy AI. They were pretty good in Splinter Cell: PT, but you can't get away with ANYTHING in Morrowind.
5: In strategy games, when one unit MUST SURVIVE AT ALL COSTS. It's ok in SupCom, but only because that's supposed to be you in the giant robot anyways, and the whole game is built around it.
6: When games come out crap and have to be patched to meet my standards.
7: Why are games so gently caressing expensive? LotR: BFME II was pretty good, and it was $10. SupCom is VERY good, and it was only $30. Anything higher than $40 for a game is inexcusable for anything less than the Epic Awesome Game to End All Games of Awesomeness.
