new program to better differentiate its diverse Wii software lineup. According to the company, future Wii games that earn a CERO C rating (equivalent to ESRB's Teen rating) or above will be packaged in new black boxes. Likely, this initiative was started due to the upcoming release of Zangeki no Reginleiv, Nintendo's first CERO D–rated game (ages 17 and up) in Japan.
It seems this is a platform-wide mandate, as Biohazard: The Darkside Chronicles looks to become the first third-party game to sport Nintendo's black packaging. By differentiating "hardcore" games from the rest of the Wii lineup, core gamers should have a much easier time identifying the titles they might like. As for helping "casual" folk make the quick decision, it's as yet unconfirmed if Nintendo will continue to use that striking red box for all Mario-themed games.
