I totally understand your points, OP. I would also say that I cannot say you are wrong.
I just prefer FPS over a little fidelity. Not in all cases though.
I prefer 60fps:
First person shooter
3rd person adventure/action
Racing games
30fps/inconsistent:
RTS,
Turn based strategy
Maybe RPGs, depending on how action heavy they are
I really think certain genres are much more fun to play with a higher frame rate, but its not always necessary. I'm sure someone has already typed pretty much exactly this. We dont have to fight.
