I was wondering if you people play any programming games? I have been into Robot Battle for years now. I have tried several other games but don't find them as fascinating. There are even contests with money prices in Robot Battle - the next deadline being 1st March 2005.

Google Directory lists several programming games and, now that I check it, many new ones too... I know that in some of the games you program with Java, that would be an asset if you can recommend any games you have tried.
