I've programmed a small game system and can announce Kobold's Quest 3.
This is a sequel to Kobold's Quest 1 and is programmed with pygame.
You can run it AFAIK from python2.4.
The story is about a kobold who wants to become a wizard, you just
destroyed the evil and the mountain pass crumbles behind you. You are
now on your own at the mountain's edge.
You can call this a roguelike if you want.
