I\'m not totally sure about the "Chest quiz" either, but it seems that certain treasure chests will quiz you...somehow, and you may get Items that help you or hurt you.
As far as characters, they didn\'t mention any Secret ones, but there are SIX playable characters, all with their own special abilities (Wild Arms like...kinda).
Get this.... You can switch characters--on the fly. In fact, when fighting bosses, it may be impossible to use only one character. Fight-switch-fight, you figure out who works when:)
Also, Some dude in a village house may want his stuff back too, in addition to just his house (ungratefull townsfolk), so when you bring his stuff you get more weapons, or items, etc.
Also, you have to arrange the town according to their wishes. Someone may want to be near water, or food, or far away from the gay guys (Yes, I\'m not making that up). They will give you clues on all this, but the clues won\'t always be so straightforward.
GET THE MAGAZINE. It\'s LOADED with info!!!!
