Castlebuilder game means that the game players do not play Castlebuilder for killing other players, but trying to build an impressive castle. However, it will 1vs1vs1vs1 or 2v2. There will be a final battle in the game after 2 hours, the total game, probably will last 2.5 - 3 hours. In the time before the final battle, players organize large and small battles and siege. Any Idea about this?
