So, as the game evolves, the villages grow and grow more. Why not adding the kingdoms?
1. Kingdom stake - claims a big territory for a bunch of villages, but doesn't protect from trespassing and stealing (it still protects from vandalism).
2. Tower building - Eats up like 10x10 paved ground, uses bricks, a load of wood, boards and uses glass. Contains a big load of stuff, has windows, a cellar and a second floor.
3. Castle - A huge building. Built on 30x30 paved ground, with 7500 stones, 50 dreams, huge amount of wood, boards, glass and other stuff. Has three floors, cellar, windows.
4. Thrones, crowns, robes - anything the king needs.
