First and foremost, Sports games, the only subgenre of Sports I like is Skateboarding games.
Racing Sims: whilst I do like arcade racers like Burnout, games in the vein of Grand Turismo bore me to tears.
Fighting: there isnt even a subgenre of Fighting games I like, I hate this genre through and through.
Horror: whilst there have been a very small percentage of exceptions, Horror is a genre I actively avoid.
FPS: I used to love First Person Shooters but now they've become to boring that i just dont enjoy the vast majority of them.
