Although Super Mario Odyssey seems to maintain that wholesome charm associated with the mustachioed plumber, it has been given an E10+ rating by the ESRB. It isn’t shockingly high, but it is the first mainline Super Mario game to earn this rating. It’s difficult to pinpoint exactly what could have led to this higher rating, but the ESRB usually releases a more detailed summary before a game’s release.
