It seems as though Square Enix's attempt to reach out to Western gamers with The Last Remnant has done little in the way of olive branch extension, with the title selling 220,000 units since its release last year. According to Siliconera (and corroborated with info from VGChartz.com), the game sold even worse in Japan, where 360 saturation is notably low, moving only 160,000 units, making the game a relative success with Western audiences.
That being said, combined worldwide sales for the game totaled just over half of a million units, with 560,000 selling altogether (more than 400k of which were sold in North America and Europe). Hopefully the acquisition of Eidos will do more for the Japanese company in the west than The Last Remnant did.
