I think they were going for Game Cube level “child-friendliness” with the 64 but didn’t have the fidelity for it until the Game Cube. I don’t think Mario Kart 64 or Super Smash Bros was any more or less cutesy than Double Dash or Melee.
Wind Waker was definitely more light-hearted than Ocarina or Majora’s Mask, though.
