I too would love to have all of the old Western buildings to create a nice Main Street in a Western town. As it is now, my Western "town" is rather sparse. It currently consists of the 4431 30th anniversary re-issue of the old grey and green sheriff's office, the headquarters building from Fort Eagle, the headquarters building from Fort Bravo, the brown and blue Steck Western house, the new sheriff's office, and the new saloon. I actually like the new sheriff's office and saloon a lot better than their older counterparts, as they are larger and more detailed.
It's a shame the Western theme now barely exists, as it is a wonderful theme with lots of play value due to its diversity (e.g. Indians, Civil War, cavalry, wagon train, town, cattle drive, railroad, mine, etc.).
