collector's edition comes with a bonus disc of stuff like making of videos
its like a special edition for movies
all it is are special features
im pretty sure thats the only difference gameplay is still the same for both
I got special edition lol... bonus disc with the making of halo 2 and all that stuff like deleted scenes. The case is made of metal lol, and It comes with a bunch of extra stuff like a free halo cup thing from seven eleven but I doubt that's still valid.
