The iOS version of Ghost Trick: Phantom Detective, which came out in Japan in December 2010, is finally coming out worldwide. Capcom gave the DS version a year to sell (or not), but the English-language version of the game has already appeared on the New Zealand App Store, typically the first sign of a worldwide release over the course of the next day.
Like the Japanese release, this version of Ghost Trick is somewhat episodic. The first two chapters of the supernatural mystery puzzle adventure game (phew) are free, with the rest of the game available as in-app purchases. We had no problem recommending a purchase of the full game on DS; it's even easier for us to command you to try it for free.
