There wouldn't be some trick which y'all are aware of but I ain't, whereby an improvement goes obsolete once a city or empire becomes a certain size?
Walls become unbuildable (but obsolete too?) with city size, but can that be done to custom improvements too?
The Forbidden Palace needs a certain number of cities to be built, but can this be added to custom improvements...and in reverse?
(I'm trying to figure out a way to provide tech-improving buildings for small civs that don't help out the large gigantic civs...)
