Ooh, that's a good one, steth. I'm curious about that as well and hope they respond to it. A similar question crossed my mind back when I was first hearing about the GAK news.
I agree, it seems like Civ is shifting closer to the immersive, role-playing AI side of the spectrum, and away from the play-to-win, gamer-mentality AI. I feel a fine balance of both would be optimal; perhaps GAK will find a better balance of them.

Also, I guess I'll refer to the expansion as GAK now since that's what Greg is using.

Instead of using acronyms like GK or G&K. (Although, it does remind me of someone going "gaaak!" after tasting something disgusting, lol.)
