This review is based on a single play as the GM. I bought the PDF, read it and immediately set up a game and ran it, which is probably the fastest purchase to play for an RPG I've ever had. The game rules are simple, but effective. Saves go against a stat, either Str, Dex or Will. Combat is rolling for damage only. This leaves lots of room for adjudication of odd situations on the fly without flipping through a book. Character creation is fast and interesting with only 4 stats and a matrix for equipment based on them. I'd love to see more matrices of stats to equipment as that is brilliant since you skip the horrible and long step where people buy all their crap during most of your first session for the ZZzzzz. We were off and playing within 15 minutes and the game runs at a good clip. I finished an entire adventure with about 6 encounters in just over 2 hours. Definitely a system to check out and try if you are interested in OSR as it's a boiled down D20 at it's core, and frankly, if you want to get into story stuff without all the annoying and confusing system crap in say Dungeon World or FATE, this will do it. Will make a very easy pick up game for nights drunk when you, as the hapless GM, get forced to run something as well!
Overall it is as if Lamentations of the Flame Princess and Numenera had a child.
