One of the Playstation 2's biggest Japanese RPGs, Dragon Quest VIII, has just been made available on the US App Store.
Everything from the PS2 version is here, reworked for iOS. So it's essentially the same game you've probably played (or at least heard of) way back when, only it's all been shrunk down to fit on your iPhone and iPad. And the controls have been reworked for touch screens, naturally.
You can download Dragon Quest VIII right now for $19.99, and the game features absolutely no in-app purchases of any kind - you get the whole thing right from the start.
