It's one of best ever used.
Generally useful for all kind of roleplaying. Even to combine with other worlds and Settings.
If someone searching for the general roleplaying system, then from my opinion, it's the best.
All parts you need are inside.
Easy Charakter generation. Fast traits, skills and soon into playing.
Precise if needed and fast in the normal manner.
Parts for every kind of lifetime. I use it in SF universe and in a Fantasy universe, but it works for so much more.
Included so much experience of Roleplaying Game Design, to make it the best possible at present, from my opinion.
It is worth the price it costs.
