I found a YouTube video with the title "Top 10 Game of Thrones Mods", and following that I've just bought Skyrim (5 minutes ago), and I wonder, in your opinion, what's the best Game of Thrones mod for Skyrim?

I do not even know what Game of Thrones is. Is it a TV, Movie or game. I guess I might have to google it.

I would suggest playing the game for a bit and then look to add mods to it.
