i think it would be cool if you could play a campaign, from reach, like a "historical campaign" or something, and you would play as john and you would have your team of spartans, sam, kelly, etc. . basically play "the fall of reach" only in game form, i think that would be cool

That would be cool, but I'd rather have Bungie spend their time developing new plotlines than showing us ones we know over again.

Yeah dude, that would be awesome, me and a friend have talked about that too, it would be amazing to do that.

i have to agree with Dark Eagle, they need to develop new plots.

It would be cool, as long as it didn't hinder the Halo 3 very much, and add the Grunt Uprising with option to play multiple sides-Jackals, Grunts, Elites, Brutes, ect.
