Nintendoland, for actually delivering cool a asymmetric multiplayer.
Mainly the three versus games:
Luigi's ghost mansion, aka spooky spooky ghosts, aka the haunt is real
Animal crossing sweet day, aka f the police, aka binging and purging.
Mario chase, aka the one nobody in my circles of local multiplayer buddies has provided a nickname for.
Honorable mentions to the train mode, Zelda game, and metroid game.
All of the above led to memorable, exciting, and unique game experiences.
