"Lightning's Shadow was one of the winners of the uDevGame 2003 contest, out of about 60 contestants. In Lightning's Shadow you control a powerful monk and hurl fireballs, lightning bolts and ice shards at your friends or at the AI. It works with multiple players on the same computer, or over the internet."
"GLFighters was one of the winners of the UDevGame 2001 contest, which only gave David Rosen two months to create it. It is not really finished so be sure to read the readme file included before you begin playing because there is no real interface. GLFighters is a 3D game with essentially 2D gameplay, David's first experiment with OpenGL. You control a GLFighter (some kind of robot gladiator) and fight with the computer or another player using swords, guns, and grenades." (from site)
