What I want:
I rather they not copy the image of the actors in the series, but follow the way the books describes them.
I would hope they separate the story lines by the characters, like the books separates their accounts with chapters, but don't make it chronologically. Just their story lines based on the books and the player gets to choose which to play in the beginning and the ability to stop where they want to and pick up another character story line from the main menu.
I want all the dialogue from the books in the game; the descriptive parts I can live without.
What I would do:
If I was head of the gaming department, then look into how many people we have on staff and divide them up into different groups for a friendly competition. Each group will get a character and their accounts from the book and they will try to write a game scenario for that character and chapters he/she has in the book. Pit the divided groups against each other and offer a nice price at the end for the one voted the winner. I believe this may show different playing styles that could be developed and placed into the end game.]
