Also, sidequests will mostly involve finding rare items lying around, like that egg in the image. You won't be able to buy most of the stuff anymore, because that was silly.
I guess only the most basic forging materials (Like bricks or something) and some of those that have usable effects (Like throwing stars) will be on sale... I guess that's good, since some rare materials are also used for quests and it'd be to easy if we could simply buy them to finish the quest... Maybe there could be some points in the game where stores have more stuff on stock for players to buy? Like you can buy Cheese at the begining of the game, but later on you can also buy Cupcakes
Ah, that's a clever idea...I suppose, while the quests will still be fundamentally the same (give me X and I'll give you Y in return), at least there's more skill involved rather than just buying the stuff.
