Hey! the guys at
http://www.opcoder.com/projects/chrono/ are doing something very similar. Why don't the two of your groups get together and see what you can do? I don't think either of your games will make it to the end alone, and i really wanna see a 3-D Chrono game. so talk to 'em, okay? :P
Our leader asked already and they politely refused. Our visions are quite different: our's is a mod for UT2004, and their's uses its own engine. Also they are doing 10 demos of different areas of the game and we are remaking the ENTIRE THING.
