Oddly enough, I had the complete opposite reaction from Iron From Ice.
I like Telltale Games, but the Game of Thrones property tries to tie in so closely with the events of Season 4 that it's almost bound by it. At least with the Walking Dead or The Wolf Among Us or Tales from the Borderlands or even Back to the Future: The Game, I felt that I was making another original entry in the universe and the consequences (or lack thereof because of the branching paths converging) felt part of its own story.
In Game of Thrones, I get none of that. Part of me always knows that something is going to happen so that the Forresters always reacting to the show canon. You know something can't happen to Margaery or Tyrion or Ramsay because they're part of the canon and the canon must be held. The characters feel like excuses just to watch them. Gared is there to hang around Jon Snow and Sam. Mira is there to see all the stuff between Tyrion and Joffrey go down. Asher's probably going to see Daenerys at one point or another. I guess the 'best' of these stories that has the most freedom to be its own material is Lady Forrester and Talia (you know, when Ramsay isn't making cameo appearances).
It really does feel like I'm playing another tie-in game again, like The Godfather game or even Force Unleashed. But Telltale has proven they can tell independent stories outside those narratives. In the Walking Dead, we met Herschel and Glenn for brief cameos, but they were written out so we can get on with the story and have it be about Lee and Clementine. (Though I'm not entirely sure Glenn or Herschel are the same ones we met in the TV series).
It almost feels like a no win situation. I didn't know Game of Thrones prior to playing the game and I felt completely lost with all the references, cameos, rules and other gobbly gook that seems almost necessary to getting the full enjoyment of the game. Now that I have prior knowledge of the series, part of me knows that whatever choices I make, half if not more of them, will be rendered meaningless because of Telltale's formula and the show's canon. In contrast, Tales of the Borderlands feels much more accessible, does not require knowledge of the series prior and the illusion of choice at least feels more convincing.
But, that's just my opinion.
