From the introduction:
Owl Hoot Trail is a roleplaying game set in a fantasy version of the American Wild West. If you have played Dungeons & Dragons, many things about this game will seem familiar.
In this game, the players act out the roles of interesting people in the game world. You might play a rough-ridin’ cowboy, a fancy man or lady, a no-good horse thief, a steely-eyed lawman, a mysterious mentalist, or something else.
In addition to humans, players can play halflings, dwarves, orcs in the Old West. There are rules for both gadgeteering and magic.
