My post a few pages back on nudity was a general point regarding HBO not specifically GoT itself, which has ample amounts in the book.
Also, my point regarding HBO having the same idea of 'mature entertainment' is that when a game once to appear 'mature' it adds in women in skimpier clothes, with bigger boobs and it swears more. HBO has basically taken this line of reasoning. In that it seems to believe maturity correlates directly with nudity and swearing.
They need a rethink before it becomes a true joke. Broadwalk Empire was brilliant but the nudity was to pull in 13 year old male virgins who lack access to the Internet.
