The reason I don't enjoy FPS is not because of its structure, but because of its perspective. When I play, I like seeing my character. I hate First Person perspective as a whole.
I don't like the structure and I don't like looking from first person, although there are games in which I think the first person aspect works great (for instance the free-running game mirror's edge)
That sounds reasonable. I can relate to that as well. But I guess for the most part, I enjoy whatever works. My friend dislikes FPS's because that pespective gives him motion sickness while 3rd person doesn't really affect him all that much
Uncharted 3 can learn alot from other games not just gears.
EDIT: Though really Naughty Dog should believe in their own self not taking other game ideas. Theres good/fun aspects in games and there are bad aspects.
