I've been playing games of this genre since the days when Commodore 64's ruled the planet - Bard's Tale, Pool of Radiance, etc., all the way through Diablo and Neverwinter Nights on the PC. I don't expect a smaller developer to equal the big boys, but I find some aspects of the game sorely lacking (and I won't even go into the mixing of genres that you discover as you explore the final levels battling the Taurax as that would be a spolier).
This game would have been better off with fewer character development options and better game play. Advancement is a little too slow for my tastes, and the rewards of battle should have been greater. It's great that you can jump between locations once you've been to key points (or gain the teleport spell), but be prepared to do a lot of walking to get there (and the back and forth between cities makes the game monotonous).
As it stands, the game tries to be too much. It would have been better with less features, more action and better character development/advancement. If they release Book III, I doubt that I'll be buying it.
