Alright well there might be a few threads like this but i thought i would start another.
My idea is that in the next halo game or actually the next game that takes place in the halo universe for multiplayer should have a actual map maker where you can build the terrain. Mess with the climate of the environment, day, night, snow, rain etc.
But along with the map maker have Forge mode separate to it. Because it would minimize glitches to overload the maps.
Also that within forge i think giving the player the ability to put in scripted/A.I. events in the map to make them more detailed.
Maybe the ability to custom paint your armour and or uniform/BDU and instead of preset colours. Have a standard 256 colour wheel and a camo preset so the possibilities of having any colour you want are endless.
Painting curtain sections of the armour/BDU would give player unique-ness is somthing that i think personally people would go nuts for.
Just a small idea. But post them up, up, up!
