AFAIK, the AI has never initiated a trade, but will accept any deal it considers fair (easiest to do by offering resources 1 to 1)

Still, the AI never trades now, but still works out OK in the mineral-centered standard universe.

For an organic/radioactives heavy race, just swap the mineral & radioactives settings, do some fine tuning later, & they should do OK.
