    longDescription = ''
      Castle-Combat is a clone of the old arcade game Rampart.  Up to
      four players (or more in future versions) build castle walls,
      place cannons inside these walls, and shoot at the walls of
      their enemy(s).  If a player cannot build a complete wall around
      one of his castles, he loses.  The last surviving player wins.
