What theme "fits" into zombies in your opinion? We play in an apocalyptic town, huge buildings in Asia, Alcatraz, the Pentagon, a Soviet cosmodrome, a mysterious jungle, even the moon! It doesn't matter what the theme or location is, what matters is the storyline, gameplay, and how fun the map will actually be. Western zombies is something we've never had, so Treyarch is trying to give us something different with each zombie map. They could've stuck with it being Nazi Zombies, but then there'd be little diversity in each map most likely. People need to try to think about the benefits of this being a western town instead of thinking "ERMAGERD, COWBY ZAMBIES, DATS STUPD!!"
