What's Your Favorite Open Source Game?
Carlos Camacho asks: "The Inkubator Project is a website for creating free, Open Source Mac games through a collaboration between experienced and inexperienced developers. As webmaster, I am interested in adding to the seven games we have listed in our link section. So, I would like to ask Slashdot readers for their picks of the best Open Source games. The Inkubator Project focuses on Mac developers, however any game project that uses cross-platform technologies is fine."
Crossfire of course! The graphics are a bit simple, but it's got nearly as much depth as nethack, and it's a MMORPG. Gameplay is a bit similar to gauntlet, but with CRPG elements.
Flightgear is fun.
