I've just recently been acquainted with Rogue Space and I'm really liking the book. It appears to be a simple RPG system, but not too abstract. I also really like the format he did his little mini booklets and preview books. I saw those and thought to myself what a great idea, I bet I could fit the Angry Miniatures rules into one of those. So I did.
In case you don't know how to put this together, I found some simple instructions, courtesy Google images.
