And yet, wouldn’t you say an acropolis, mosque or step pyramid as places of worship would be at odds with the rest of the look? It’s too obviously inspired by one part and time of the world. The intention may be to leave things ambiguous and vague, but I just don’t see that working in practice. In an alternate world, you can of course mix and match anything if you like, but this kind of stark contrast isn’t used at all in the current build.
Most such Medieval city builders have churches in them, so I wouldn’t expect any drama about it. Though I absolutely understand the want for a deeper system than just another need of your people to be fulfilled (mechanics-wise), instead of just copying those builders. But to pretend this could just as likely be set bordering the Aksumite or Ghana Empire than the HRE or Poland? The architecture, climate, flora and fauna, technology used, it all points to a certain time and area. Players can’t really decide to set their village into 17th century China or 2nd century Rome, because it looks nothing like that!
So when adding a “prayer hall” or “community hall”, I still think it should look like a Central or Northern European Medieval church (which already includes a vast range of styles), because everything else is done in this style. What really is the problem with that?
