First off, awesome job 343. My only gripe is that I spend too much time scrounging around for weapons and ammo in the campaign. It almost feels like survival horror at times, but for me that takes away from the pacing of Halo. Also, more frequent checkpoints at places would also be greatly appreciated to avoid lengthy backtracking. I noticed both of these minor complaints have been made by critics.
Other than that I am absolutely loving the game. Multiplayer is better than ever. Thank you for keeping Halo alive for me and legions of fans. Great job!!!
