Cowtown Creator
The Knuckleduster Cowtown Creator from Forrest Harris and Knuckleduster Publications is a real treasure for the Western GM.
Here’s a review at RPG.net.
The Cowtown Creator hits me in several sweet spots. First it focuses on the real Old West instead of the movie/myth Old West. Whether your game is about the gritty realism or zombie-gunslingers, injecting some actual history is always a plus. Surround your zombie-gunslingers with accurate historical detail and disbelief is much easier to suspend.
How it conveys this historical detail involves my other sweet spots. Harris begins by describing various types of Western towns and examples. He even gives samples of the types and numbers of businesses you’d find in those towns. Next he takes us through each type of business, from the Cattle Yard to the Saloon, the Fancy House to the Barbershop. Along the way he offers floor plans (often based on period drawings and photographs), sample workers and customers, and colorful anecdotes out of the history books. As this is a system-free book, all the characters are presented in a descriptive paragraph rather than any kind of stat-block.
There are lists of business names, drinks, prices, and (my favorite) names culled from historical documents. And Names there are a lot of names. Thousands probably. More than you’ll need. [I used the names list to create a random name table that I'll post soon.]
In the back are a couple of system specific add-ons for d20, Deadlands [classic], and FUDGE.
And yet I still can’t convey how great this book is. It’s one of those that you grab when you’ve got a few minutes to skim something. Hands down it is the most useful Western RPG book I have.
