A few suggestions after playing the 3B demo (some are general suggestions as well):

The Korath, Iconian and Krynn colors are too similar. It is difficult to tell them apart on the minimap. The colors should be reworked.

For some reason the AI will request to trade expensive tech for cheap tech. For example the Drengin traded me Star Federation for Xeno communications. This was also very early in the game, and I doubt they could have researched Star Federation by that time. Something is messed up with the AI tech trees and what they research.

Is it just me or does Galactic Privateer look just like the Research Center. If you are redoing some of the graphic, consider doing another one for it.

The research cost for Aquatic world is too cheap for the Krynn, the research cost matches the Torians which is incorrect.

The AI seems obsessed with Miners. The Torians and the Terrians in my game have all their planets filled with mining ships. I am playing a large map with common everything.

Thanks!
