I believe these are all mostly brillant ideas. As for 2 disc this is even better! Now take into hand of how cool it would be if forge world was what its name persist! An entire forgeable plant that you could pick and choos small areas os the cutomize. Thus not making a fully customizable planet as work in it may be come dull. Though a rather merely miny map of maps. Halo 4 should be just like Halo: Custom Edition in a way, how awesome wouldit be if we could forge in space mega ships and sett them on a small course and have space battle on and of both UNSC and covenant ships alike! As the hype for Halo 4 increases will have to wait,hope, and see.
