So maybe that's what caused my super low income? Too quick an expansion without the proper economic structures in place to support it?
I've never turned worker automation on myself, since that's one aspect of micromanaging I tend to enjoy. Based on what others have said, and on my observations of the AI's lands, the computer loves cottages for most of the game, then later on will focus on food to the exclusion of all else, even tearing down fully improved cottages (I believe it relies on pumping out Great People to do its research). That's one thing I'd fault it for, the other two are:
- It has poor prioritization and strategic planning. I don't think it communicates with its build-planning script, so it doesn't, for example, save chopping its forests for key wonders. It also doesn't seem to realize that an impending invasion means you need that mine operating now, not another cottage, even though you'll need both eventually. Nor does it understand that railroads, as Yosho mentioned, give a production boost to mines, lumbermills, and oil wells, and won't prioritize building them there.
- It always builds the resource-access improvement, even if you have plenty of that resource and no viable trade partners. Dye, incense, silk, furs, and uranium all produce less commerce with plantations/camps/mines than fully improved cottages, and a railroad plus mine on stone puts out more hammers than a quarry. But the computer will keep building the access improvement regardless of how many you have or what the relative strategic values are.
