Seriously ever since i started playing Halo i always wanted to play my own character, not like online play like how you just make your own armor and stuff and not being able to edit skills (Grenades, Asault rifles, pistol, etc.) and in a Halo MMO you could do that. I know it may have been canceled, but does that really mean they can't bring it back?! If anything a Halo game where you just make your own character and explore planets as you please, like a RPG. I really think that could make a 10/10 game. Only time may tell.
