Are you sure you're thinking of
that game and not A Game of Thrones: Genesis? The latter was developed by the same studio a year earlier than the RPG and appears to be universally hated.
Not that the RPG is perfect or anything—at a few points I had NPCs hovering around like they were standing on a Roomba while they threatened my characters, which undercut the gravitas of the situation somewhat—but the story ties well into the lore and arguably has a more earned and tone-appropriate climax than the show itself. Also, the texture work isn't great, even for a 2012 AA game, but everyone has weirdly elaborate teeth. I don't know why I'm mentioning that, but it's 100% true.
