Well, if you are doing RPG stuff - you need classes: Fighter, thief, wizard-type, assassin, barbarian, knight, paladin - all those usual types. Then you need villagers/commoners (old/young) - then custom villager types - blacksmith - inn keeper - barmaid - shopkeeper. Could even have good and evil versions of characters. That sort of stuff.
You already have quite a selection of building content.
What about a road system? Sections of road that you can build up a road system to join your towns. Maybe a few different texture styles of road - straight pieces, bends, crossroads, etc.
Not many games go that far - in fact, has any RPG game done it? Normally they just blend the textures into the landscape. However, personally, I would custom LOD the road sections over the terrain.
