Ah, you wish to buy them for the novelty factor? Yes, I do believe they are probably reprints of some sort. When I was rummaging around for them on Japamart, I noticed that many other animes have similar 'set pieces'.
Mm, indeed there is! However, I'd prefer the art in digital format. XD There's something just spectacular about Yocky's work - I feel he really captured the original book cover artist's feel of the series, unlike the anime/manga. A superb choice, on the developer's part.
Oh, quite a compliment. XD It's funny, I'm not even sure what rope me around the series. It was well written, yes, but it's not incredibly special. I do, however, feel it needs much more love than it garnered. The English anime has not done it any justice, whatsoever.
