We ran the Children of the Dragon game on a nice little opensource program called OpenRPG. It works quite well if not a little slow gametimewise. I put up links to downloads for the three pieces you need. Python is the main program what runs the OpenRPG executable. wxPython is an addon for Python that was used while creating OpenRPG, therefore it is needed as well and must be installed after Python. After all that, you need to download and install OpenRPG.
Links good as of 1/24/05
