I don't care for FPS that much either even though I've played several on PC. Just never got into it very much. A lot of it is that its just the current trend.
If you look at history:
NES era - platforming popular
SNES era - still platforming but also RPG era
PS1 era - remember all those fighting games that came out? Toshiden, Tekken, Virtua Fighter, etc?
PS2 era - ?
Current era - 99.999% FPS
