The Metro series. I'm a curious adventurer in games and I love to take my sweet time, so the mask/filter system (a.k.a. being timed) proved itself a nuisance and killed any interest I had to play it.

Tomb Raider (2013), on PC. The camera shake really got under my skin, but after finding out there's a patch to stop it, the game had proven itself so mid to me that I couldn't be arsed to take that extra step to keep playing it, and just gave it up.
