It's a little sad that the wild west has fallen off as a setting for films. When Clint Eastwood's Unforgiven came out, I remember some referring to it as the last great western. Looking back at film history, there's a deluge of movies taking place in the era.
I suppose it falls into the category of American Exceptionalism--what, in story terms, separates America as a nation from others. How men from very little will often rise to the occasion and become a hero in the face of evil. That's what I'm told, at least. I'm Canadian.
What is also does is offer the modern gamer a glance at a time where survival skills, honor, and reputation were the things that defined a man.
Maybe I'm reading too much into it but the western is a fantastic place to show the rise and fall of our favorite characters.
Except that Insane Clown Posse movie "Big Money Rustlas." That doesn't work as an example of anything. Entertainment included.
