I've never understood this - it's like they insisted on some bizarre approach to AI creation (a trained neural net or something?) and then flatly refused to add fixes by hand. I'm not sure how else you explain screwups like "will trade 9 gold now for 1 gold-per-turn over 10 turns". It's like they understood the concept of a loan but got the system backwards. Or military strength judgements, which are blatantly just running on "number of currently active units". You can be feared for having lots of spearmen in the Industrial Era, but the ability to crank out 10 high-end infantry per turn isn't even present in the assessment. It's a bizarre and embarrassing weakness for a series most people play in single player. These aren't grand strategic errors, they're "make the number bigger/smaller" errors that random modders handle vastly better than 2K.
