I'm not a huge fan of western RPG's, and I really have no hopes at all for this being an awesome game. However being a huge fan of the books, and TV series, I have to admit i'm pretty excited to play this one. Not only that but it does have some good things going for it. For one it's being published by Atlus, and 2 George RR Martin is helping write some of the script.
Apparently its a completely new story, taking place in the same time period as the books. You play 2 parallel stories involving 2 of Robert Baratheons bastard sons. Eventually the 2 stories merge into 1.
Anywho, here's the trailer.

Edit: Just noticed an easter egg at 1:52 in the trailer, hahaha. See if you can identify who it is
