Had some good times with this one. Excellent for learning the basics in good old game development with SDL.
I adore PyGame. It really took me back to the days of programming games on the ZX Spectrum! Managed to knock up a crappy Manic Miner rip off in a weekend with a little knowledge of Python and GIMP. Documentation is a bit patchy, and you will need to know a bit of programming before creating the next cross-platform Indie smash hit, but if your looking for a dev kit that will enable you to muck about with sprites and sounds, then I strongly recommend this.
A great intro language for those interested in the basics of game programming. Recommended for anyone wanting to try game programming.
