| I liked the SWG way of handling this :
- few terrains are really prone to having "cities" (not enough "flat" constructible flagged fields)
- limitations of X houses per terrain zone (or continent, whatever)
- first come, first serve
- promotes tradeskill importance (need to create plans and submit them to your local mayor in order to get acceptance, or something)
- could be destroyed via PvP (ressource fighting mostly)
