10 Things in games that annoy me

In no order whatsoever 
 
1:Doing hours worth of unlocking,playing a story mission,and the game crashes at the finishing cutscene [i'm looking at you Saints Row 2] 
2:Dying repeatedly at the same point in a mission from the same thing [be it a stronger enemy or a game mechanic] 
3:Timed challenges [usually higher/last tier of difficulty] which make you have to be absolutely perfect in playing, otherwise you will fail no matter what [Mercenaries 2 Eg: Fionas challenges at tier 3] 
4:Automatching on the PC [mainly RTS'es] where it pairs you with Elite players when you play online [<_< Dawn Of War 2 Eg: Me rank 1 - him rank 30] 
5:Holes in enemy AI logic [sometimes it's hilarious/helpful, sometimes a pain in the neck] 
6:Retarded Friendly AI [Do I really need to explain this?] 
7:Pricks online who brag and then are shown up to be bad players, and then trying to cover that up.
8:Enemy AI which can see you from a mile off and then kill you with a pistol. 
9:Grinding 
10:HOW DID YOU KNOW I WAS THERE?!
