Okay this is just my little rant with the whole Halo series... Halo was a mediocre FPS on a console with ZERO GAME SUPPORT. (XBox at the time of its release had very few good games.) It got ridiculously over hyped and made out to be something that it was not. Then Halo 2 came along and was an absolutely terrible game. Also it was 'noob'd' down. Halo 3 was a minor improvement upon the two but I still believe it is not the same caliber of game that CoD4 is. I've always not been a fan of FPSs on consoles. That's just my opinion though.
