Die-hard, (ancient) Dungeons and Dragons 2nd Edition fanatic here.
That said, I bought and learned (and taught my preteen children) Cubicle Seven's Doctor Who relatively simplistic RPG in 2013 . Savage Worlds is incredibly similar to this mechanism (enough to where I am assuming at this point that Cubicle Seven was HEAVILY influenced by this product, but I could be wrong), and once I obtain their "Space 1889" (of which I have been a huge fan for over 25 years), I plan on spreading the good word, so to speak.
I believe that this system is a must-have for RPG aficionados, especially for those who are looking for a rules system that provides an incredible range of flexibility for the Game Master - story telling versus rules lawyering.
