Lost Planet is clearly an attempt to appeal to the western market, as Capcom keeps farming it to western developers. The strategy doesn't seem to have caught fire like the company hoped, however, as Lost Planet 3 failed to meet sales expectations.
The recent Capcom financial results state it plainly: "Sales of 'Lost Planet 3' (for PlayStation 3, Xbox 360 and PC) were below expectations due in part to intensifying competition in the European and U.S. markets."
Capcom itself isn't doing too shabby as a whole, though. Monster Hunter 4 for the 3DS was a monster success in Japan, and other titles like Dragon's Dogma: Dark Arisen, and Ace Attorney 5 hit their sales targets. On the whole, net sales were up 7.2% from the same period last year.
