From the back of the book:
"Howdy Pardners and welcome to the Wild West!"
Gunslingers and Gamblers: Streamline Edition is a role playing game set in the Wild West of 1876 which uses the Streamline system first seen in Privateers and Pirates (also from FJGaming).
Characters can be tough cowboys, skillful bounty hunters, honourable lawmen, slippery card sharps, Indian braves or just about anything else you can imagine . . . .
So saddle up, load your guns and it's time to get rich or die trying!
