There's a ton of the procedurally generated features I haven't "discovered" yet I bet but for a quick look at some stuff I've come across:
- Courtyards
- Courtyards but divided by little stone walls per house
- Benches and chairs
- Shrubs and bushes
- Towers
- Archways
- Those things you put a coin into and then look through in order to get a magnified view at some distant point of interest
- Mailboxes
- A beehive!!
