I think it would be fun to have a more customized Command and Conquer. My brother's gone so far as to suggest a RTS like command and conquer where you deal with a zombie virus outbreak, or you could be a dark organization that is trying to use the virus and do some kind of 'zombie herding': Command and Conquer: Biohazard! heh... I would like one that's more RISK like, with research paths and dealing with mass production of units. Would be fun if we could all do some sprites for it and build such a game.
