I say that for forge bungie/343 should add spawners for AI's; I mean it could be elites it could be marines and grunts etc.. I know that people will want to just want to spawn kill over and over in order to get credits if there is a credit system that's why either A)You have um come by a dropship that requires like 30meters of open space or bungie gets rid of the ammount of credits you get during forging or custom game whenever there is an Ai spawner. Now I'm not good with the finer details of this scrumious plot, But I think its a good idea. Also with forge you guys could make it a complete terrian edditor on a small scale that way it won't take up 2 gb of space. Or on a large scale(players should have choice of how big or small). Like I could make an entire covenant base and an entire UNSC base that gets simple AI's and set a large group of Ai's to be on attack or defence and the spartan(you) has a mission like capture the flag or king of the hill while UNSC forces help, and on the covenant side they could have Players playing as elites. And it would be awesome if you could play by yourself as well. Like If I'm an elite the UNSC gets a spartan or multiple spartans(depending on how many the human players outnumber the spartans by)Lag may be an issue but with advancing technoglies it should be possible to keep a stable lag-free game online depending on connections.
