Yep making a really good AI is the wargame programmer's Holy Grail and so far no one has mastered it. Someday I'd like to be able to turn an AI on to a harder level where it actually plays smarter rather than just having a lot more stuff to throw at us. The AI difficulty buttons always remind me of the old George Carlin joke about the tv brightness button - "I turn the bright button up all the way but the tv never gets any smarter".
I'm really glad to hear that you may be able to put some time into improving the AGE engine AI. I know that with a series of games that things improve with each game in that series. Will your AI improvements get into NCP or BoA as well?
Is there a place where I can get my hands on some kind of manual about the AGE engine scripting language? I'm starting to think that I should learn it since I really like the AGE engine series, despite my complaints, and it would behoove me to learn the scripting language so I can mod scenarios.
