Wooo, Old Command and Conquer back! You sent me down a nostalgia trip with this game. I loved old C&C. The art is pretty cool and I really liked the audio. The audio is perhaps the second biggest part that made me remember old C&C.
My only gripe was that in Skirmish the game was really laggy and I wasn't able to play well. That said, the amount of work you must have put in a game like this... that is a lot of work. Gotta say, well done, great work! You captured the old feel pretty well.
