I just finished playing Game of Thrones yesterday, actually, and I really liked it. I don't have much to add that everyone else hasn't already said - great, mature story; interesting characters; good voice acting (especially Mors); good mood; linear gameplay; and enjoyable combat. It feels very true to the Game of Thrones license, and I couldn't help but feel I was going to be screwed from the very beginning, despite my best intentions. I played it on the Xbox 360, so keep that in mind.

If you like linear, story-driven RPGs, give it a try.
