Oh, there is no doubt this would be a lot of work any way you look at it. And, the work wouldn't yield any profit because only a few crazy fools like me might take advantage of it.
The simplest way to accomplish what I'm asking for would be for Malfador to document the structure of the savegame and turn files. Then, I could write a program that would let me figure out what was going on in the game by reading the savegame files and programmatically construct a turn file.
Hmm... now that I think about it. I know there is an Open Source Version of Civ called FreeCiv. I wonder if you can write your own AI for it?
