I wasn't sure what to expect when I bought this as I had just recently found a DM I liked and he offered to run this game. I am always willing to try new RPG's as I find the major ones to be getting kind of stale. So I bought this mainly on his recommendation and the fact that it was very cheap. I was pleasantly surprised.
The main thing I like about this game is the simplicity and how smooth the system seems to run. On top of that there seems to be a good bit of realism in the game. The only major negative that comes to mind is that the book is hard to use as a reference in that specific rules are hard to find when you need them. I didn't like the fact that the game is based in London though that isn't anything against London it is more that I don't like it when a game system insists on the setting being in one place. The simplicity factor is that the the game uses one type of dice which is the six sided dice. When you roll you either have a success(4-6) or you don't have a success(1-3). You get several dice depending on your stats and the point is to try to get enough successes to accomplish what you are trying to do. There are no levels to gain which I like a lot. You improve your character by increasing your skills or your stats. You also create a dragon character and a scion character which is a dragon that has forgotten his true nature and lives as a human. I thought this was a unique and cool concept that I haven't seen before. In addition the combat system is fairly intuitive and really simulates combat pretty well which is where the realism factor comes in.
Overall I really like this game and I haven't been this enthusiastic about a game in a while. The only reason it didn't get top marks is because of the less than optimal editing of the book.
