Classic is timeless.

There's really nothing on the server begging to be medieval or anything close to it, and there's railroads, burgers, etc. If there's supposed to be some kind of theme here, nothing's committed to it, but I think that's part of what Classic is.

A mall would be cool. A marketplace or bazaar would be interesting, but where would it go? North Graal would be good! Get rid of those pointless buildings and replace them with a marketplace and you'll have killed two birds with one stone!
