This review is the complete mess here. Last Remnant is simply the best (or at least one of the best) JRPG of the new generation, and I'm not a fan of JRPGs anymore.
The game offers great content, great battle system, an average storytelling and has not eve 10% of the technical problems this angry reviewer wrote about. It has as same texture popup as Mass Effect (maybe less) and about the same slowdowns as Fallout 3 (and they only occur during action scenes of combat). Voice-acting is also average, but the music is simply awesome, the best I've seen in the last years.
This, however, is indeed a complex game and it won't appeal to casual players because its fun is within farming items, hunting rare monsters and defeating incredible difficult bosses. This poor reviewer from IGN is probably one of those frustrated gamers with only knack to casual games or with inner hate for the japanese gaming industry.
