Using few defensive units would be great, but, (as I have played a few games in debug mode just to see how the AI plays) the AI somehow "knows" which city of yours is the least defended and make a beeline for it, then the next worst, and so on.
Also, I have a feeling I know what the answer to this question will be, but I'm not sure. Can the AI research techs faster than 4 turns? If so, then I really don't see the reason for it, or, for that matter, making the minimum research time 4 turns for any player (especially for Accelerated production.) Or, do the AI just trade techs as soon as they get a new one?
