Disclaimer: forgive me if somehow I've never run across these. I've played a lot of RWG maps and haven't seen these.
There are some large-style POI's that I think would give immersion and maybe another layer of depth but that I haven't seen in the game yet.
Large shopping malls
Airports
train stations (with RWG-generated tracks!)
sports stadiums
RWG interstate highways that connect to the smaller roads. maybe just one such highway would be generated per map, and it would cut through more or less in a straight line.
College Campus (with dorms)
Farms out in the middle of nowhere with much larger fields rather than having the farm basically in-town which is kind of weird, honestly.
