do 3d, it'd be much more interesting. This all sounds possible with blitz, but it would take a lot of time, especially the networking. You would have to create a server, potentially your computer to act as one, or buy a computer to act as a server, which if the game is to be commercial, would be ideal. I don't know much (anything) about networking with blitz, but as long as blitz can do local and global network changes (display different things per computer based on a set of variables global to all players), this oughta be possible.
