Trash men and scheming women come to provoke him? They only end up getting slapped in the face. While other players are still trying to figure out the game's mechanics, Ryan has already built a top-tier luxury hotel, gathered four beautiful maidservants, and is comfortably lying back, waiting for Doomsday to arrive.
