Looked over every piece of art: it's a relatively good package - you get a lot here, but only if you don't have any other editions.
Fullslip here repeats HDZeta WEA steelbook, while the steelbook is the worse of the two recent WWA ones. It's like the Studio CE's fullslip, while whitish steel inside that is better.
6 art-cards are exactly the same, as those included in CE, and the booklet looks to be entirely the same by the design of the spread and cover.
All that's newish is 5 poster cards, but two of them are actual poster in the CE, and some (7) screenshots on photocards.
So as having an HDZeta DL and a Studio CE is better, than this one, I won't be buying.
