I downloaded this game and I must admit I found it to be a delight and well worth the money I spent on it. It's very evocative of the feel of Bruce Campbell / Sam Raimi movies (Like Army of Darkness set in the Rockabilly age daddy-o!). Even if a Game master isn't interested in using the system "as is" the game background would transfer very easilly to any universal role-playing system. I've used it as a supplement for a friend's GURPS game as well as in HERO system and conversions were a breeze.
What I appreciated most is that this game is complete as a one shot purchase. Unlike some other game companies (White Wolf / Wizards of the Coast, anyone?) you don't need to buy a bazillion, expensive, supplements just to play it properly. The core book and some dice are all you need. I give this my highest rating! It's a must have if you like campy role-play, rockabilly, or retro culture. The art is very distinctive as well.
