Robowar is a great freeware game for the Mac. You test your brains and programming abilities against other players by designing and coding virtual robots. Twice a year the tournaments are held and everyone sends their best contenders to compete for the crown. The robots are written in a simple stack based language called robotalk.
Hopefully here is a link to download my Tournament Analyzer. It allows you to take a tournament log and find out how your bot performed including how it did against each opponent. Stats include: kill and survival score, average time for kills and death, bugs, collision deaths, and suicides.
