A portion of an NWR interview with Executive Producer Ryogo Tsujimoto...

NWR: Are we going to see any significant differences between the western and eastern releases?

Tsujimoto: The fundamental game is the same. Think of Monster Hunter 4G versus Monster Hunter 4 Ultimate, we want to bring that full experience to players in the west. One thing that has to change is that for licensing and rights reasons certain collaboration dlc items that we have got in the japanese version we're just unable to bring them over to the west. But of course we wouldn't want to just cut content and leave western players hanging with a less complete game so we've actually taken the time to create some exclusive new collaboration dlc only appearing in the western version of Monster Hunter Generations so even japanese players won't have their hands on this stuff. We've already announced Fire Emblem crossover equipment, we have the Okami wolf costume for the prowlers, for the cats. we also announced ghosts and goblins crossover content and we have even got further unannounced collaboration dlc that we're gonna be announcing in the coming months, so stay tuned for more news on that.
