I have got to wrap my head around what we are missing... or what we need to add.
My current thinking is that we need to add 3 levels of special building for each era, at least as a starting point...
So Eras:
Classical
Medieval
Renaissance
Imperial
Industrial
Modern
Special Buildings
Bell (Village Hall, Town Hall, City Hall) + era in front of the name
Cross (Shrine, Temple, Cathedral) + era in front of the name
Education (School, College, University) + era in front of the name
Culture (Tavern, Pub, Great Hall) + era in front of the name
Research (Salon, Study, Library) + era in front of the name
Naval Building (Pier, Dock, Harbour) + era in front of the name
Are there any other specials I am not thinking of?
Then one of each of these (rather than all three) for the Ancient era too probably.
We can give them some fairly boring generic names to begin with, then later on we can modify the script, change the names and reapply the changes, especially once we know a little more about what will actually get spat out of the generator
Step one make it work, step 2 make it fancy
So you could plug those in and see where we are up to.
