I like most game mechanics to some extent. Creativity in combining game mechanics is key to making an outstanding game imo.
However, I don’t like things that force a time limit. I play games as an escape. I don’t like feeling stressed by a clock while I’m off the clock. These can be literal timed missions or things like a food/water meter. Escort missions also suck for similar reasons.
I think difficulty in a game should come from overcoming a foe, traversing harsh terrain, or solving a puzzle. If the game is hard because I have to stop what I’m doing to feed myself, or I have to rush to complete an objective on a timer, it just becomes work.
