At E3, Nintendo showcased numerous 3D versions of games we've played and sometimes loved before. Star Fox 64 in 3D. The Legend of Zelda: The Ocarina of Time in 3D. A bunch of 8-bit classic Nintendo Entertainment System games.
They all appeared on the 3DS. Some, like Star Fox 64 3D were playable, with updated graphics. Others, like Pilotwings Resort, seemed like more of a sequel. Others, like Ocarina of Time, were presented as non-interactive videos made of better game graphics than the original.
