I don’t get it. Why does anyone care about any game that much?

Actually, the plot outline is the same and the major events are the same (as the books). GRRM gave the show writers the major plot points and D&D said their show has the same ending as the books, they just arrive at it in a different path because of the time/budget constraints associated with television production.

I hope someone goes after the online bullies and gives them an eye-for-an-eye.
