"E for Everyone" DOES mean that a game could be enjoyed by adults, but it doesn't mean it will be enjoyed by adults. The target audience for most Nintendo games is young people. Even if there was a T-rated Nintendo title, I could assure you they would be targeting the 13 year olds rather than the 18 year olds. It's that soft image that made Nintendo not a power player in the hardcore gaming market despite attempts to market Wii U towards hardcore gamers early on.
