The second thing is extensive use of humour.
I haven't read trough it all yet, but there are two thing that I've learned from start: a) it has some minor typing mistakes, like some parts not being bold that should, I found price for 1 weapon missing on one chart (but you can look it up in other, so there is nothing really wrong with it).so general little mistakes that appear after someone has printed the book. To play the game, you'll need D10s (it says at least 20, which means I'd need more, hehe), some colured tokens, a scatter dice and, being a miniatures game, miniatures and some terrain. I will dress it in plastic 'shirt', just to add to its protection.
The pages are stapled together, so the book won't fall apart as easily as some of the other rulebooks I own. The rulebook is 80 pages long soft-back book, A4 size, which I, guess, is pretty common.
