I just browsed the entire thing, & I have to say, it is quite impressive. It is comprehensive, well-formatted, & nicely written. The author has done an incredible job of making a pastiche of all the Final Fantasy games into one combined campaign setting. The mechanics are not exactly d20, but they are rather close, so it won't be hard for players to make the mental conversion. Some things I don't agree with, & others may not work as well as they are intended to, but overall, this is excellent.
