Best FPS game of the 2000s

[captain carot]

Neither Metroid Prime nor Fallout 3 are FPS.
Fallout 3 is an RPG. You can play it without guns and even try playing totally peaceful (pretty tough though). Or you can use VATS which makes it more or less turn based like.
Metroid Prime is a 3D Action Adventure, more precisely a 3D Metroidvania.
