Warning: LOTS of spelling errors and a few incomplete sentences. very few rules gaffes, but the spelling and grammar errors were a bit of a downer.
Ignoring spelling and grammar, this book awesomely captured the feel of a Gritty Low-magic world, while still adding all the bells and whistles one would expect from a high-magic campaign. Combat was fun but lethal if you weren't careful (don't let ANYTHING get the drop on you!) the classes each had many fun class abilities and uses for action points (which the system uses), and the Magic use in the game is hands-down my favorite magic system of all time. I warn you, it is a complex magic system - not "calculus" complex, but it does involve a bit of prep work for a wizard to develop some spells for use ahead of time. I prefer a list of pre-done spell effects and just modifying those on the fly for range, area of effect, etc. so that I don't have much work to do in-game.
I wrote up a play example in a thread on RPG.net's d20 forum a few weeks back, but can't find it now...
