After looking through that, there were several moments where I just thought Diet Dr. Pepper. Phantoms instead of the Halo 1 dropship, adding another Spartan II, adding new Spartan IIIs, changing weapons, adding alien species, changing there appearances... I'm sure Bungie will be able to tie all this into the canon (I hope), and beside those few minor things, I feel like Halo: Reach will be my favorite game of all time.
