As though playing Civilization IV won’t be bad enough, I found this little snippet in an interview.

Civilization 4 will be the most moddable version of Civilization ever. Players can edit basic stats and attributes in XML files. On a higher level, much of the game will be exposed to Python so modders will be able to edit events and have more control over how the game works. On an even higher level, we are planning to provide an AI SDK to allow experienced programmers to dig very deep into customization.

Wow. I’ve always thought it would be great fun to create a new AI for Civilization or some similar game, and the fact that the SDK might be Python-based is just gravy. I can see having a ton of fun with this if they actually follow through on this plan.
