I've been playing this game for about a month now, and it has quickly become one of my favorite games ever.
As I understand it, choosing the Neutral alignment makes all upgradeable tiles instantly usable. Building the Orbital Terraformer achieves the same effect. But, I'm still quite confused about some things even after searching through the forum and wiki. I find that if I research the terraforming technologies (Soil Enhancement, etc.), not only does it make the unusable tiles usable, it also improves the planet quality. For instance, let's say my planet has planet quality 10 with 1 yellow tile, and I research Soil Enhancement. The yellow tile becomes green, and also 3 orange tiles appear.
Basically, my question is does choosing a Neutral alignment have this same effect? It seems to me that the terraforming technologies improve the planet quality, but does Neutrality (and Orbital Terraformer, but I think that project is a waste) achieve this same effect?
