I took Steve's advice and signed up for PlanetMULE. I played two games against A.I. opponents. I came in last place in my first game, and second place in my second game. The game is a blast and I plan on playing the C64 version soon. For some reason, it plays fine on my emulator, but crashes on the real 64. I will have to troubleshoot that. The Mac version I have is pretty slick and easy to play.
