So I finally got around to playing the Snathi campaign, and it's pretty funny.
Balance-wise, their tech tree has three hub buildings (e.g. Slave Pit, Molecular Fabricator) at the cost of star base range extensions. This seems like a fun tradeoff, but having extra hub buildings isn't so great when we're stuck with PQ12 planets in a game with no Ultra-terraformers.
I understand Ultra-terraforming was OP, but could you consider buffing Terraforming to make to make PQ<16 planets useful? One simple fix would be to Copy-Paste the Biospheres building a few times (e.g. Biosphere Alpha, Biosphere Beta, Biosphere Gamma, Biosphere Delta).
DO THIS AND WE MIGHT SPARE YOU FROM OUR VENGEANCE!
