One of my favorite themes in Board Games is the Wild West. I've always enjoyed Western Themed TV shows, movies, and books. I'm not really 100% sure why. I do know that it was heightened when I moved out to Colorado.
As an historian I also love Western history (when I get around to reading it).
This means that most games with a Wild West theme are automatically going to gain my attention. There is something that I like about how it in my mind feels so "open".
Now I always judge a game based on more, but I will always take a peak at a game if it takes place in the American West.
What about you? Do you like Western themed games? Why or why not? What theme are you obsessed with?
