Got this game today, and even when starting the campaign i had to go back to dashbord to change from 1080p to 720p because the frame rate on 1080p is just horrible. Very very laggy. Story is short, not like the original Halo. For the "Most anticipated" game. With all those adverts saying "Remeber Reach" i hope that Microsoft "Remeber" that the game is very bad and a total let down to the halo franchise. I have all he halo's and really like them, i'm just very dissapointed with the game in general. Online has been inproved, more modes, upgrades, new weapons. Alot similar too Halo 3 really. If i were you, anyone who is preparing to buy this, i'd save your money for something better.
