@xXxGuitar511: But you are a human, this plot is total different.

@Doom: As I haven't ever heard about "Destroy all humans!" (but I already thought of a fun game when I heard the title), but I heard about FarCry, Doom and FEAR, you are disqualifying your argument yourself.

Almost every successful shooter of the past few years had that "hero saves the world (or whatever)" plot.
This supports my argument.
