They can add more of a variety of game modes. Griffball should have been day one. There are lots of other modes missing from even Halo 2 if u look deep enough.
More weapons, which isn't that hard to do outside of balancing them.
More maps. So tired of seeing games ship with only a dozen or so maps, how about 25+ of them? Well I guess we can thank DLC for that.
I'd like to see bots in the Halo series so me and my friend can simulate some halo MP matches rather then going on vs the randoms. I know that's a long shot but w/e.
Longer single player campaign but not by much. I don't want it to drag but I don't want it to be over in two nights either (outside of Halo Legendary of course where I still haven't finished it.)
It's just that simple.
