At the end of my games I see a statistic that says "Credits Lost to Planet Underdevelopment". I usually have a line that goes way up on the graph, meaning I lost LOTS of credits. The AI loses minimal credits. Now, I always build mining stations for crystal and metal, then build a trade port for each planet as I acquire them. I also upgrade the civic tech tree so the metals/crystals are extracted more efficiently. What am I doing wrong that I lose so many credits over the course of the game?? Is it that I need multiple trade ports at each planet? Thanks.
