America didn't "get western", it was when they started colonization of the Western side of the country. Because all the immigrants had landed on the Eastern side of the country it took longer to become 'civilised' hence it earnt the name "Wild West". Also this map pack also features MP maps, if you're just buying it for Zombies it seems like you're taking away 2 thirds of the game.
