The Legend of Zelda: Four Swords Adventures
The Legend of Zelda: Four Swords (GBA) and The Legend of Zelda: Four Swords Adventures are both included on the list (GC). These were two independent games that allowed up to four pals to battle around Hyrule as four Links dressed in different colors.
That initial Four Swords encounter, which was originally featured in the GBA port of Link to the Past, was only available in multiplayer form until an improved port included a single-player option and was made available on DSiWare for a limited period in 2011. (and later very briefly on 3DS in 2014). The GameCube sequel was a complete retail release in its own right, catering to single players. This allowed each player to freely explore a dungeon without interfering with their fellow adventurers, resulting in an incredible multi-screen asymmetric multiplayer experience long before the Wii U was even a glimmer in Nintendo's eye.
