In the same way, there isn't any proper competition for games suitable for under 15s on Xbox and PS4. Only Nintendo seem to target "family friendly" in a satisfactory way. As always though: Nintendo have picked a market share that other companies are ignoring.
I saw the gameplay for Mortal Kombat 11, and I thought: "Hmm... maybe that's a bit much". So maybe just I'm getting old?
*Looks at Bayonetta 2 and 3, DOOM, Wolfenstein 2, Warframe, Outlast 1/2, Octopath Traveler, Mortal Kombat 11, etc*
I mean even Xenoblade 2, a 1st party game, is filled with adult humor and mature themes. Sure many of Nintendo's games can be played by all ages (adults included), but that tired argument of your lost meaning a loooong time ago. In fact, I would argue it only really pertains to the Wii era as Nintendo allows all kinds of adult games on their consoles.
