Not sure how many of these are appropriate for the thread, but:
-"Daily Quests" in games that have an online component. What I hate is that they force you to do something that you might not be optimal or even a good idea. Tetris 99 for example often has quests that are "get several 3-line clears in a single game" so now you have to go out of your way to do this and it might not actually be optimal and in fact by the time you're done accomodating it, you've played yourself into a bad position. Fortnite has something similar where some quests require you to use an inferior weapon for EXP.
-The lack of manuals in modern games, them having absolutely need-to-know components that are never explained to you--for example: "tricking" off of jumps in Mario Kart 8 to gain speed. The game itself never tells you about this, in fact I had to watch a youtube video to even know basic stuff like this. A youtube video should not be serving as an instruction manual!
-When a game has a knockdown animation/state, in a lot of games I'm annoyed at how long it can take to recover. I remember this being something that annoyed me in Breath of the Wild.
-When I swear I pressed the button but the game ignored me. Seems to happen a lot in 3D games.
-I've made topics about this, so I'll keep it short: Horror games where the twist is that the horrors your facing are actually brought on by the player character's personal trauma and/or some bad thing they did in the past. Worse is when its said or implied the entire game was a dream or a hallucination.
