Any battle royal or survival game - PUBG, DayZ, Ark etc. Played a lot by the people I game with, I just can't find any enjoyment in any of them. I think they’re just stupid. Boring. Frustrating. Zero enjoyment at all. I wish I liked them just to play with my buddies, but I rather not game at all than play a BR/Survival game.
Starcraft 2 - I absolutely love watching pro games (either vods or tournaments with good hosts), it's just awesome to look at the high level of skill displayed by some players. But playing it myself, it's bronze league 4 life. I just can't play it. I'm way too slow, my macro/micro sucks, my army control is pretty much select all->attack. I suck so bad at it which is a shame looking at how much I enjoy watching it. Out of self protection I just don't play it anymore. Massive ragequits.
Fighting games - Like SC2, I love watching pro's, but when playing myself I'm unable to land a single punch before getting hammered down.
WoW - Started playing in 2005, on and off since 2011 or so. Can't do the commitment anymore. If I play WoW I want to play hours on end but due RL that's a thing of the past.
The Division - Sank a ton of hours into this game. Looks amazing, plays amazing but it's just bad. The devs cant figure out what to do with it which is a shame.
