Will, you be releasing updated versions regularly?
Will the initial version work with PS3?
Will the game speed be same as UT, or will it be as fast as C&C Renegade(which means slower)?
Does the idea of initially releasing barebones version of the mod that will have the most basic things and textures, and will initially use most of the textures and assets from UT, that will be replaced with the proper things through regular updates appeal to you?
