Zangeki no Reginleiv In Development For Over 3 Years
Nintendo's first Japanese M-rated game is about to launch, after 3 years
Producer Hitoshi Yamagami revealed in an Iwata Asks interview that Nintendo's upcoming gory action game, Zangeki no Reginleiv, took over three years to develop.

The game, formerly known as Dynamic Slash or Dynamic Zan, is scheduled for a February 11 release in Japan. However, Zangeki no Reginleiv originally began development between the summer and fall of 2006, prior to the Wii's release in November.
Yamagami also spoke about the debate surrounding just how violent the game would be. Ultimately, the development team justified chopping off limbs because it was of mythological giants, not real people.
Due to the violence in the game, Zangeki no Reginleiv is Nintendo's first CERO D (ESRB M) rated game in Japan. Nintendo is shipping the game in the first Wii black box, with perhaps the best box art ever. The hope is color coded boxes will help parents find appropriate games for their children easily in stores.
Zangeki no Reginleiv will launch in Japan on February 11. No North American, European, or Australian dates have been announced yet.
