Marvelous: Mouhitotsu no Takarajima (Marvelous: Another Treasure Island) is a Nintendo developed and published action RPG that was released in 1996 for the Super Famicom. The game was never released outside of Japan, presumably because the Nintendo 64 had just been released and Nintendo of America and Nintendo of Europe would think that their respective consumers wouldn't respond too well to a game released on the SNES that wasn't part of an already established franchise.
The game is known for being the first game that Eiji Aonuma was involved with. The Nintendo designer would go on to head the entire Legend of Zelda franchise, directing many of the top video games in the series such as The Legend of Zelda: Ocarina of Time, Majora's Mask, The Wind Waker, and Twilight Princess.
The great Captain Maverick was a pirate of legend who kept his treasure called "Marvelous" hidden that could only be found by those who were willing to solve puzzles that many deemed unsolvable. A group of children, however, will use their wits to prove them wrong when they go to the island where the treasure is said to be held. A group of pirates, however, have similar intentions.
The game is similar to the SNES classic and best seller The Legend of Zelda: A Link to the Past. However, rather than controlling one character, the player will control three different boys (Dion, Max, and Jack). You are not allowed to name each individual character, though you can give a name to the entire team in the beginning of the game. Like A Link to the Past, Marvelous is seen through a bird's eye view.
