I played it, but I'm not really a fan of it.
Melee combat is pretty bad, magic system is very interesting (having to draw runes on screen), but very unwieldy to use in the middle of combat... meaning one will prepare and use the same spells over and over again (especially Harm).
The setting didn't really capture me either.
I'm a huge fan of Dark Messiah of Might & Magic, though. It's a very linear game, but has the best first-person melee & magic combat I've ever seen in a game, and very good level design.
