The game of thrones board game (2nd edition). I've read the prologue of the first book, never seen an episode, but boy do I really enjoy the board game. It's like Risk, with a bunch of complications. There's a website we've been playing it on called swordandravens, so we can play for days at a time, and you just get an email when you're up. Highly recommend!
(Sorry if this is not for board games as well, just popped up on my feed. Although this kind of counts as a video game anyway in this format.)
