I did run a short-lived game of my Wild West/Fantasy setting a while back. So maybe you're thinking of that?
Rivets Eternal is sort of my baby since A) I'm working with a semi-well known comic book artist to write a Rivets Eternal comic, (shhh.

), and B) I think it's the best setting I've created. But my Wild West setting is fun as hell too. So really it all depends. We'll see Friday.
I hope more people post with thoughts cuz I really plan on having this game last the long haul (like these games on ENWorld that are in like part four, five, ad infinitum). So I want some real thought to go into it.
