Finally got to watch the pilot last night on my DVR. Never read the books (not much of a fantasy guy) but MAN I enjoyed that! Half the fun for me is learning how the world "works" and spotting the differences in armor, building style, etc.
Off-topic, but I'm also watching "The Borgias" on Showtime and I had to watch the Sunday episodes of Borgias and GoT back-to-back last night... My theory is that, aside from doggy style sex, non-basic cable shows also need incest, because there's some weird brother-sister thing going on in "The Borgias" right now as well.
