I threw out three hooks: protect a wagon train of settlers planning to go through hostile territory to a new settlement, try to eliminate a dragon for the local cattlemen's association, or track down the wanted criminal Nasty Canasta. They chose the third.
Savvy readers who had awesome childhoods or who are awesome parents may recognize that name. I stole the character from Looney Tunes (Drip-Along Daffy, where Daffy and Porky try to rid a "typical Western town" of said villain). And funnily enough, although I didn't plan it to go down this way, it actually did play out in a similar manner to the cartoon I stole the idea from!
I also got to try out a simple "stud poker" mini-game that can be played by rolling dice to determine how good your hand is and then betting on it. It's not perfect, but it's simple and worked well enough in practice. With a bit of tweaking it could be used to simulate other types of poker as well. And it fits in well with the Cheat subskill of the Dastard skill set (which both Jeremy's PC and the NPC Nasty Canasta had).
Another successful play test! Oh, and Jeremy has been making some art samples that I think look pretty awesome and will likely be licensing from him to help illustrate the book when I get it ready for publication.
