2007 for Wii: You have Super Mario Galaxy, Super Paper Mario, Mario Strikers Charged, Lego Star Wars: The Complete Saga and other titles.
If we're going by North American release dates, it would have to be 2013 for 3DS. Fire Emblem: Awakening, Animal Crossing: New Leaf, The Legend of Zelda: A Link Between Worlds and some other titles.
So, it depends on what your rules are since you didn't specify original release year only.
Honorable mentions:
2001-2004 for GameCube
2010 for Wii

You can count games according to when they released in your region if you want.
