From the introduction:
Now, this place's pretty simple. The West is a land of plain people, horses, cattle, and guns, with some booze thrown in to keep everyone sane. There ain't no high-tech spaceships, no fancy magic, and no fools in capes (well, maybe ponchos). It's a time of stoic, lonesome heroes, dastardly scoundrels and the peach-faced boys who just want to make a living with their families out here on the Great Frontier. A place where a man's word is his bond (unless sittin' at a poker table), where the greatest issues of the day are decided on the main street at high noon, and where the only things you really own are your horse and your gun. Welcome to the Wild West!
