My batch of Korean Import arrive today, and surprise surprise, it comes with the much sought after artbook :-
But from what I've flipped through, it's like all other freebies today. Nice to have, but nothing to scream home about. For one, it's very flimsy and have about 2 pages dedicate to each character with bios, some linearts and promo arts and that's about it.
Could take a few pix of the contents when I'm back at work tomorrow if anyone is interested.
