well i've got a fair few pet hates.
1) not being able to install the game on my ps3. WHY WOULDN'T YOU LET ME CUT DOWN THE LOADING TIMES?! WHYYYYY?!!!
2) cheap deaths from mistakes. i'm looking at you dante's inferno. if you fall into the water/lava/whatever, you die instantly, no chance to jump out, just plain death. do what arkham asylum did, if you fall into a gas area, allow me to grapple out at no cost to me.
3) boring quick time events. button mashing is fine with me, rotating the analogue stick is fine by me, however killing a boss by pressing like, 3 buttons is boring. if you're gonna make me to a QTE, make it interesting.
4) games where there is no way to select level/backtrack. this mainly applies to when there are collectibles around. you then find out you missed one by like 10 minutes, and you've already saved your game and the bridge behind you is destroyed. great, i now have to play the whole fuckin game again, just for that one item >_>
5) as many people have said before, escort missions. they aren't fun, especially if the AI is a pile of wank.
6) forced vehicle sections. the amount of times i have not been able to complete the hardest difficulty because i can't do the one cocking vehicle section that is forced (i'm looking at you black ops, resi 5 and crysis).
7) also said before, unskippable cutscenes. in particular, long ones before a difficult section or one that you die a lot on. worst of all, cutscenes that are not skippable after you have completed the cocking game!
8) enemies in games that ALL know your exact location, after killing some far away guy silently. it's just bad design, for all the enemies to know your location after something like that.
i think i will add to this later, when i remember more. i'll be editing this post when i do xD
