In their version of Walking Dead the game gave you a illusion that your choices mattered because it is its own story. With Game of Thrones having a pre-set story that illusion isn't there because this game has no effect on the overall story nore does it matter what u do in it.
Don't get me wrong happy you enjoyed it, Its just IMO it was shit due to this.
That's why I hope if Bethesda does make a GoT RPG it takes place after the Book/TV series. I guess it could be alongside it or before it providing the story it gives is good.
My issue with Telltales GoT was like I said it removed that illusion that your choices mattered.
