They'll probly do it like VG and have certain zones or chunks or whatever their going to called open bits of land that seem to join together in DF for housing.
Thats why I quit, skills should be earnt not bought. Still, no other game is like this. Had good times there. If they did an ultima 1.5 (like 2 except not if you know what i mean) i'd definately come back. Cause it's definately not about graphics.
