210 pages of pretty much support for this idea!?! Yea, the forge is very crunkified. Everyone has many ideas for different maps they want to create; right now we have a pretty good set-up for it, but I think if these ideas were ever incorporated into halo 3, or some new halo..or however its done, it would be great.
Keep on keepin' on with this idea I think its worth 30-60 bucks. I know I'd pay around that for it. Time Splitters 2 had one of the most awesome map creation systems I can think of (well really the only one I ever messed around with), but lacked the multiplayer that comes with halo 3 (due mostly to the fact that PS2 wasn't networkable like our current consoles!)
Anyway, its a great idea. You could not complain about there not being enough maps to play on, in fact with these ideas incorporated into forge you most likely could not get around to playing all the great maps out there.
