I haven't tried it out yet and probably never will. I was never really too into the Halo series (even though I own and have played Halo 2 and 3, and just own, but can't play a broken Halo 1). I never understood what was so great about it, but I am way more of a Nintendo fan than a Microsoft fan, anyway. I definitely prefer the Call of Duty series to the Halos, considering I have well over 100 hours of gameplay on MW2, maybe 2 and maybe 2 hours on Halo 3 (I only really play when one of my friends HAS to play a game of Halo with me). I just thought the Halo series was an OK series, so I won't be checking out Reach anytime soon (although I heard it is going to be better than the others).
