It's good. Graphics are dated and it's done in the Unreal engine, but I've never considered graphics as a selling point of RPGs, so what the **** ever. Voice acting might seem a little weak at times, but the major characters are all voiced well.
The story probably makes a bit more sense if you're well-versed in the world and storyline of George R. R. Martin's A Song of Ice and Fire, or maybe I should say it might be more favorable if you are? Or maybe it doesn't matter. A good story is a good story.
Gameplay is similar to Dragon Age: Origins, so people will enjoy it, or people will call it the worst thing since... Dragon Age: Origins.
