Like their Wii counterparts, mature-rated 3DS games in Japan will have black packaging.
Last year, Japanese gamers might have been surprised to see Resident Evil: The Darkside Chronicles packaged in a sexy black box, but there is a reason for it: all Wii games rated CERO C (basically Teen) and higher had to have black packaging to make them stand out.
As it turns out, Nintendo is carrying this policy over to the Nintendo 3DS. Super Street Fighter IV is white, but Splinter Cell is black. One wonders if this policy will ever cross to the western markets. It didn't for Wii, but with a new system, you never know.
