It's pretty good. But the pace is just so slow I don't feel apart of the story. Maybe it's because the only chance you get to move your characters around to interact is during the fighting scenes. I liked Shadowrun Returns better because it was much more interactive and you could walk around and talk to characters as you saw fit. Though I think Sean Bean is the main character's voice, so that ups Blacguards for sure!
I'm playing on my 13 inch Macbook 2010 and I have to have the setting all the way down, and on a low resoltion, to make Blackguards playable. But it does work and looks fine.
Good voice acting
