Has a lot of annoying quirks in combat. IMO, Low Magic Age is a better representation of 3.5 combat, and it's $15. Granted, I'm sure KotC 2 has much more robust gameplay/story, etc. Either way, this is not a $45 game. It's a $20 game at best.
I'm having a blast with this one. If you love navigating the DnD/OGL ruleset, and like the Infinity Engine games or Temple of Elemental Evil, do yourself a favor and pick this one up. Very excited for the future development on this one.
