This excellent work is one of many "base system for free" PDFs that you'll find on the market, but you won't find one as thoroughly documented, well-laid-out, clearly written or downright useful as Active Exploits Diceless Roleplaying. The basic systems are quite simple, and the additional systems (for magic, psychic powers, and so on) are solid. As with all "generic" games, you are going to have to set up your own color and requirements in the setting, but the system is easily balanced. In addition, the PDF is very well-organized and a joy to use either on the computer or at the table. It is easy to find what you need relatively quickly. If you are considering putting together a game and want to try out a diceless system for it, give Active Exploits a look.
It also helps that the work is compatible with a lot of other excellent Precis Intermedia work, making this a good investment to improve the value of those games and supplements as well.
This game is everything it says it is, gets the job done solidly, and it's absolutely free. Since I can't think of a way to improve it significantly, I give it five stars.
[5 of 5 Stars!]
