And no, the price is not also a typo
No, this is not someone trying to make a quick buck with some off brand Nontendo 3DS. This is Square Enix putting Dragon Quest IV up on the (fertile testing ground that is New Zealand) Apple Store and misspelling it.
While also charging $18.99, in typical Square Enix fashion, for an oft-ported, 24 year old game. Should be a few bucks less when it ends up on the North American store.
Square just recently announced the port.
