177 pages? So this is actually good, huh?
No joke, this is probably the closest to a proper "IE game" that I've played since the IE games - possibly including IWD2, honestly. It's not perfect; it's bugged to hell, there's the socjus shit, there's tons of vestigial stuff (weapon focus feats without weapons and vice versa, references to things that aren't in the game, etc), some flat-out unfinished/unpolished stuff (Crusaders get worse spellcasting, Ecclesitheurges cannot cast spells in armor, etc., yet neither is mentioned anywhere), the writing is sometimes absolute shit (but most often it's perfectly OK, and occasionally good, so it evens out), it's not remotely balanced (but it ends up being in a good way), and the way the game is using alignments is just absolutely fucking bananas.
But at the end of the day,
is it good?
Fuck yeah it's good.
