I'm looking for a way to play Space Wars in a single player mode. Space Wars was probably the first video game that I ever played, so it has a special nostalgia for me. But, I'd like to be able to get in a game or two even when I don't have a friend over to play. The original was two player only and I seem to remember have the same problem back in the arcade, sometimes.

Searching around, the most promising thing I've seen so far is that the Vectrex system version of Space Wars had a single player mode. I'm thinking of trying to set up Vectrex under the MESS emulator to try it out. I've always liked the vector games, so I'll probably try to get Vectrex emulated one way or another.
So:
Any other options for a single player Space Wars?
Anybody know if the Vectrex version of Space Wars single player mode is any good?
And finally: Is MESS the best way to go for Vectrex emulation?
Thanks,
Sammy
