Another super idea! Still, I’ve got a few questions/suggestions.
Entertainment:
Have you considered that some ancient peoples were very late to accept the idea of gladiatorial games, and some never did with any degree of enthusiasm? Do you intend the “Arena” to be available everywhere?
Also, have you considered that horse racing was more popular than gladiatorial games and that also accepted virtually everywhere? I am of course hinting at a building “Hippodrome” or “Circus”.
Community:
I am not quite sure what you mean with “Stadium” – is this meant to be a horse racing track or the Greek
Gymnasion? If the former, good, see above, but then you absolutely
need to add the gymnasion for all provinces where Greeks live. It was
the single most important building for Kreek city live and for the Greeks’ cultural identity, an educational facility, athletic exercise ground and bath rolled all in one. It is kin to the grand Roman baths, but sufficiently different – and quintessentially Greek – to absolutely warrant separate treatment. Where the Roman bath was relaxation, health and hygiene, the Greek gymnasion was hygiene, health and education (lots of it), almost totally without any representational overtones, and indispensable for a Greek citizen’s cultural identity.
