Don't you mean Game of thrones looks like skyrim? By the way the game is terrible. Good thing I rented it. You think skyrim textures are bad on Xbox? Look at game of thrones. It's terrible
If graphics mean everything to you, then yes, it is terrible. I haven't played it, but I've only heard good things about its story.
On topic: Skyrim looks like Game of Thrones because that style of fantasy is popular now, and it also fits the Nordic-themed land of Skyrim. Cyrodiil looked like LOTR in some ways, because that was popular when Oblivion came out.
