Theoretically. In practice, Mario and Zelda are games where a rather blobby avatar is guided through platforms, labyrinths and puzzles, where some of said puzzles consist of autonomous moving blobs that try to touch you, and which you can defuse by touching them with your active end (the front--mid-sword-swing--for Link, the bottom--mid-jump--for Mario.)

Saying that the games are about princesses and mass-murder is a statement on about the same level as saying that chess is a game about military tactics: it might look decorated that way, but it's not what you spend your time thinking about when you're playing, and it's not what draws people to the games.
