Hello, I began posting a new tutorial for Pygame on my website. Here is the first post: http://eli.thegreenplace.net/2008/12/13/writing-a-game-in-python-with-pygame-part-i/
The aim of this tutorial is to be the next step in complexity to the existing tutorials, but taking the readers to a higher level. Therefore, it's starting point is also quite high, as it assumes a knowledge of Python, basic math, and even some familiarity with Pygame. In the hope that others find it useful as well. Eli
