I finally created (and shared) something that wasn't produced for someone else's game system. Cowpokes is a rules light game set in a fictionalized version of the “Old West." It's not intended to simulate anything. It’s just a quick and easy way to tell stories with friends. It uses four stats (Gaze, Grit, Gumption, Swagger) and a 2d6+STAT mechanic and that will be familiar to anyone that has played a Powered by the Apocalypse game (e.g., Dungeon World).

Included are the rules for creating your Cowpoke and playing the game. Choose or roll randomly for your gear, gun, and hat. Too "scurred" to shoot straight? Take the edge off with some spirits. Be warned, though! Spirits may steady your nerves, but they're not without other effects. And what would a Cowpoke adventure be without a bevy of threats including deadeye Sharpshooters, speedy Quick Draw Kids, and villainous Robber Barons?
There's also a scenario to get you started: Showdown at the Triple V. Will you help your patron, C.W. Tungsten, fend off the Edison family and their pet law officer, Sheriff Brennehy? Or will the sheriff and Edison hired guns make short work of your Cowpokes?
Regulators! Cowpokes! Mount up!
