The funny thing is the age chart kinda affirms that this meme actually has some truth to it:
It looks like Nintendo struggles a bit with children as they get to age 12/13/14/15/16 because thy are likely drawn more towards "games they shouldn't be playing" like Call of Duty and GTA. But we see as this audience ages more towards 19/20/21/22, Nintendo's userbase in that age demo skyrockets.
