I like Game of Thrones TV show. I decided to give it a try to this game since it was given free to all psn plus member. My impressions are:
1) Story: it focuses it in Forrester family. It is a parallel history from season 1 and season 2 of game of thrones.Very short. Sometime it seems to go very fast, some very slow, some with plenty of details, other missing details. Overall, very acceptable. It is a 12 hour game the most. However, it has a great replay value since the decision you make will affect the course of the story by much.
2) Graphics: a horrible port from ps3. Terrible graphics.
3) Music/Score: similar to the TV show.
4) Gameplay: it is like any other game from this developer.
The game should have had allocated more budget. I imagine that by the time this game was developed, they were aware about the TV show will have, in this sense they decided to go save and allocate the budged they considered may cover any risk. However, I think, today, they may decide to go to a more elaborated game. It is like hitting the floor, can't be missed.
