After reading the AAR, I have 2 questions.
Will the main biome changes as terraforming progresses? Because if it starts tundra, it should switch to something else when made more habitable.
What are the limitations of construction factories regarding ship building. They seem to workaround the huge trouble, cost and time to retool slipways, so there must be something ?
subsidiary question: Why a single biome per planet? Big bodies should have severals, and they each can be a sub compartment of the planet. Imagine you land in the great plain of Erewhon, and then fight your way to conquer all the planet, down to the last place of resistance, the Deep Forest of Styrgia. That would be cool!
ps: anybody played Freedom in the Galaxy, a 1980' boardgame where planets had several environs to fight for or conduct missions (as the game featured an evil empire against rebels)
