A really neat preview you could just almost run the game with! The notes on the cultural significance of the Hobos of the 1930s and their place in the American psyche alongside Pirates, Cowboys, Knights and Ninjas is a really insightful look at the whole idea of the traveling independent and the American dream. I love the way this was written, and I think it just might sneak its way unobtrusively on my table.
The Qags system is not complicated beyond a couple more stat words to bring the men of the rails to life, and a bit of a magic system. The background fluff fits together well and holds up to my tired scrutiny anyway. The opening comic sets up the whole feel of the book, and the story in bits and pieces throughout of a Hobomancer's introduction and initiation makes me want to read the novel.
I can really see why this got an Ennie nomination!
