Stronghold: Crusader is the stand-alone successor to Stronghold, meaning you don't need the original Stronghold to play it. It takes Stronghold out of Europe and into the Holy Lands, giving it a tighter focus and a more exotic flavor. The economic missions that had you racing against the clock to fulfill contrived objectives have been removed from the game. Instead, Stronghold: Crusader places more emphasis on the fine art of defending or storming a castle. After all, isn't this what you want when you pick up a box with a knight standing in front of a castle? When players first looked at the box for the original Stronghold, they probably wouldn't have guessed that they'd be spending their time accumulating 500 units of cheese.
