Interesting. I've seen the AI go for crystals. But, it seems to do so only when it can get multiples. Because there is a significant hit to your diplomatic relations when you are trying to ascend, maybe the AI only goes for it when it thinks it can overcome the diplo-hit.
If somebody hasn't mentioned this yet, would it be possible to allow colonies to build "older" (== cheaper) versions of labs and factories and so forth? I often will build down-rev ships on newer colonies to get stuff out faster, but it is a little depressing to have to wait for a top-o-the-line structure to get built on a new colony because I have no option to churn out a more basic one. It would be nice to have a tab view on the planet management construc
