Since I've been talking about this so much I'd like to know if its even remotely feasable for you to do.
I'm talking about externalizing AI inputs and responses into text editable tables. This would allow Users to make tweeks and changes to try and build a better mousetrap...
MoO3 did this extensively (if you have any knowledge of MoO3 that is). I think SEIV also allows for some form of this, and even SMAC and probably the CIVs let certain 'traits' be modified in text files, though I'm not sure how much impact they had on the AI.
If you've been following the long AI thread you probably know better what I'm talking about, I've babbled about it in other threads as well
