I see your point but to each their own I guess, one of my other favorite games is Something Unlimited and pretty much it's the same scene every time with just a different DC character.
If I see a scene with Sansa I expect to see similar with Daenerys, I would love to see more of the scenes with different game of thrones characters even if that would be "echo scenes", because I play for the universe and characters I loved from tv series and books, not originality. If I needed this I would play some original games like Aurilia or Seeds of Chaos but asking for originality in a parody game? That's not the reason most people play it, they play for the characters and universe. It would be awesome, of course, but I would rather see more characters than scenes variety.
Just look at other parody games and you will see that most of them follow the same pattern, because this is what most fans want to see in a first place.
