Truly, this is one of the most criminally underrated RPGs of all time. And I'm not even fan of the books, or the show. I've always been baffled by the low ratings this game got when it came out.
I had to pick it up again because it was so good when I played through it years ago. You even get to meet G. R. R. Martin as a Merlin-type character in a lab deep in a castle.
