This is an excellent RPG system! It is currently my favorite system beating DnD 20. Why? It's simple and logical but not brainless. Easy to expand and convert.
Heck.. It's even FREE! If I knew this system was this good. I would have bought it. But now it's free. I have more money to get the expansions... (which plugs in nicely to the core rules).
Bad faults? Well not really faults.. It wont have the fancy wancy graphics and stuff (but U do get a cover). And the tables are minimal. You'll have to get the expansions. but quite usable as it is.
