It was not any more expensive than the previous two limited editions I ordered. The artbook has a standard hardcover but the prints on the inside are higher quality than your proverbial stock paper. As for the music, it is what you expect from the Fate franchise, high-quality ethereal songs with a haunting choir similar to Yuki Kajiura, Kalafina, and Yoko Kanno.
On a side note, I saw an episode of Exiled From Paradise that you recommended to me. Honestly, I will pass on the series because I do not like this blend of three-dimensional computer-generated imagery trying to mimic authentic two-dimensional hand-drawn animations. The blend looks completely unnatural and what has turned me off from shows like Berserk, Blassreiter, Golgo XIII: The Professional, and Knights of Sidonia. Thank you for the recommendation though.
