Metroid 64 would have been a Metroid game for the Nintendo 64. It was revealed in an IGN interview Nintendo that they were unable to come up with any ideas for the game. Instead of a game being released on the Nintendo 64, the next Metroid game, Metroid Prime, was released for the GameCube.
- "I know that the American people have been eagerly anticipating a new Metroid game. I have been asked about it many times! Even through the entire Nintendo 64 period we were thinking of ways to produce a new Metroid title. We couldn't come up with any concrete ideas or vehicle at that time."
