Bussard

Another interesting find this one. Bussard is a space-flight programming adventure game. That does indeed sound cool, though the game seems to require quite a lot of knowledge and patience. It's not for those who want some fast action, but could potentially be a really nice and unique adventure for those who want to invest the time in it. It's still in early development, but is playable.

A unique and interesting concept, to be sure.
