If this generation hadn't opened the flood gates that cause this saturation of this genre.....
FPS - They've become repetitive. boring and there's too many of them. Also they're not as interactive as other genres like Adventure, and Beat-em-ups.
WRPGs - I just can't relate to them. esp with the story. I honestly tried to like them such as Fable but I just couldn't.
Sim Racing - Racing games that use too much logic and realism in the physics department sort of takes the fun out of "beating" the other racers. (i.e. mario kart, f-zero, and Excite Truck)
