Soil Enhancement, Habitat Improvement, Terraform
Aphrodisiac, Orbital Terraformer
those are the planetary improvements gained from the terraforming branch. A civilization with neutral alignment would not have any use for them.
Since population bonus cap is still there, Aphrodisiac is also useless.
Instead of going after that branch, it might be better to just pursue xeno ethics earlier.
I'm happy I guess.. since I play neutral quite a lot. Still wondering what the heck Neutrality Learning Center will do and if it's better than Invention Matrix and the later research buildings..
