Thanks for all of the kind words. I had lots of free time a couple months ago, but unfortunately have been real busy lately with a change in job and location.
Good news is that I have recently figured out how to build external libraries with Python very reliably and so will do a tutorial on "Python Scripting with Artificial Intelligence Chat". It will show how to add really smart NPCs to your game by importing, customizing, and using a Python library.
Here is a simple example program using the module. It can make for some really funny chat sessions. If this causes anyone errors, please let me know to help better troubleshoot.

The tutorial will also show how to setup a Python dev environment so that end users don't need to install Python to run the game. I just started on it so hopefully will have it out in another week or so.
