**END OF HALO 3 SPOILERS**
i agree, commands and better AI would help alot. i prefer games where you have 1 or 2 AI buddies for some of the game, sometimes having alot of buddies, and sometimes having no buddies.
also, i think there will be another series that takes place where halo 3 ended, most likely will not encounter any more halo installations and you will have to survive on the planet that the ship at the end of halo 3 is heading towards.
