Since civ3 games are often so slow, the automate production feature is pretty nice, except the governeer is so incompetent at making the right choice!
For example: I'm producing either modern armour or city improvements in all my cities, and what does the governer orders to produce? Mech Infantry! It takes the same number of turns in my cities, or only a turn less, and mech infantry much weaker than modern armour.
The same story can be hear all over the ancient era. I wish you can disable individual units from being produced.
Too bad we don't get production bonuses from selecting auto governer cuz at least the AI does...
