Anyway, am I the only one here interested in the subgenre? I know Paeter found a couple of interesting talking points in the recent Cowboys vs. Aliens, but he is correct in saying that they really didn't do anything with them after bringing them up.
I bring it up because I'm getting ready to start an online, play-by-post rpg using a setting that's like a cross between the Wild, Wild West (TV series) and the X-Files called 'The Eerie Exploits of Ranger Co. X.' I'm really looking forward to it, and the character concepts so far are really intriguing: A Choctaw Indian deserter from the Confederate Army, a Chinese railway worker, and a time traveler who's stuck in the 19th century (think Doc Brown).
THIS is what I'm geeking out over now!
