Sports, shooters, games with in-game purchases but are otherwise free to play, racing games, platform fighters, games with no clear cut direction to go... yadda yadda yadda
-Point N Click adventure games
-MMO(Before 2009 ive played them a lot)
-Any Baseball games (Its not just because that sport not very popular on Europe)
I hate games that were really good but then went F2P and all the retards started playing (TF2) I also hate MMORPG's that try too hard to not be WoW (ELDER SCROLLS ONLINE, SW:TOR)
Puzzles are dumb.
Anime influenced games are dumb.
Games that try to call themselves "Simulators" are dumb (especially Goat).
Real Time Strategies aren't dumb but boring.
