I think that 343 should add forge in halo 4. but enhance it ALOT. I have a few ideas of what they could add. They should add pelicans and phantoms so you could get around the map alot easier, and you could invade the enemy in awsome sexy ways. You should be able to add ai`s in forge that you could program to move around using waypoints. and they should add a texture feature, where you can change the texture and color and style of the buildings(like be able to make a brick wall or a wooden wall instead of a really annoying forerunner metal wall). They should also let you be able to make your own actual maps where you can like make an island or a forest or an ocean you know, an actual professional map. also more weapons and vehicles like scarabs and carriers. and you could choose to make elites, grunts, brutes, hunters, drones, jakals, skirmishers, and even prophets for the AI`s. I know it would take a long time to make and it would take up ALOT of memory on your 360, but I think they should at least add the AI`s.
