Hmmm. Looking at this, we could force-specialize the AI. If we pick the 'correct' specialization depending purely on planet size (economy for small, industry for medium, research for large), and then stacked the 'right' building choices, that would potentially lead to a much stronger planetary AI while we're waiting for Froggy to add in local awareness.
It could do with some tweaking and that did cross my mind, although I'm not sure how effective it will prove due to the fact sliders are set on a global level. There are definitely some improvements that could be made however.
Take a look at the growth worlds. I fail to see the point in the AI having a food world, I've seen these in action, why the AI needs a planet with 6+ farms I have no idea, especially since they more than likely don't have the approval for them.
