Do people need Nintendo to be so specific that they have to actually say "Titles like Senran Kagura, Doom, GTA, Killer7, Life is Strange, Call of Duty, That Dragon Cancer, Papers Please, MGSV, Dragon's Dogma, Gone Home, and other titles"?
Especially when some of the titles aren't even Mature rated to begin with. They may be Mature in subject but that doesn't automatically make them a Mature rated game.
Nintendo also isn't saying that they exclusively want anime stuff and all "pervy" things. The games are examples of some of the things that Mature can mean and they even mention Doom which is like at the opposite end of the spectrum. Yet most people only seem to see Senran Kagura.
