i think aqueducts still give them more housing, but i may be wrong. the half-cost campuses are the seller here. At worst, your observatory will be +3 if you surround it with farms. that’s still pretty good considering you get it twice as early as a theoretical opponent with a campus. the only thing maya could benefit from is a builder to start imo, because I agree they may have a slow and difficult Ancient era, but my guess is the classical era will make them snowball really hard. They look really good.
