I love Kingdom Builder, the expansion Nomads is the hammer. Since Crossroads can not keep up in my opinion. It offers 4 new landscapes, new location tiles and new tasks. Addition there are now knights, ships and vans, which can pull over the game board. Not a bad thing, but basically not much new. Nothing you could not even reach the port and coupling (base game) or caravan and stone wall from the Nomads extension. All in all worth it in my opinion not far behind the expansion and also does not make as much fun as the other games.
