Right.

So, the suggestion would be to make numerous variations on the facilities in order to allow more types of upgrades, as long as you pre-planned them and could figure out the new upgrade system. Apparently some players think this would be worth the effort, because they really would like to be able to upgrade amongst the many different sizes of cities and so on with more freedom than is currently possible. In theory this could be done, though in practice it would be a fair amount of work, both to implement and to figure out and use in play.

The Colony Cultural Centers were to allow insane manic players to try to build one or more cultural centers on a homeworld or colony where there was already a space yard. This was back in an earlier Version of the mod when homeworld cultural centers had stacking spaceyard abilities, but the hard-coded limits thus prevented them from being built on a planet which already had a spaceyard. Therefore I added the colony cultural center. Later I decided to remove the SY ability of homeworld centers, so the Colony CC just became an atmospheric variation. I think it's still in the mod, but now requires research in colonial development in order to be able to embark on the massively long-term project of actually building one.
