I say none of them do because they're all flawed and there are better FPS out there, the first Halo is probably AA at best but Halo 2 and 3 don't even deserve a single A.

You seem pretty obsessed with this subject. Show me on leo-j where Halo touched you.

*Face Palm*

The first for Innovation, the second and third for high production value.

Yes. They do.

Please answer my question.

Yes... all 3 of them do. That doesn't make them the best shooters ever but they are all 3 very well made games.

Yes, they all deserve AAA status.

if u take only the multiplayer part maybe.

but story it should get even a 6.

What an absurd, blatant troll thread. Of course, all three of them do. In fact, if I was a Sony fan, I'd go out of my way to point out that they are AAA titles. If Halo 3, as you state, isn't even a single A game, then you're a fanboy of a company who can't make a single game with half the sales of a single A Xbox title. Run along.
