Actually, I don't see myself 'using' any of these LE bonuses - they will be folded up neatly and stuffed in a closet somewhere. If you live in Tokyo, hit me up and you can have them for free. The digital contents in the Premium Box (an in-game costume for Firis and a PS4 theme) will see the most actual use. I just like giving Gust money - I wish they would do something like the Ar nosurge Limited Edition again, though. That one didn't just have a bunch of anime girls on clear files/posters, it had a music box that fit in well with the game's theme of song magic. For Atelier, I don't know, maybe a couple collectible flasks or potion containers would be nice? I would use those.
Now if you'll excuse me, I've got some alchemy to do.
