1998 was pretty great, for Nintendo and the entire industry: Ocarina, 1080, Rogue Squadron, Banjo-Kazooie, F-Zero X, Turok 2, Body Harvest, Tetris DX, etc.
2000, with Perfect Dark, Banjo-Tooie, Excitebike 64, and Majora's Mask, is pretty great too. Same goes for 1994.
2010, if Xenoblade is counted, is damn impressive also.
I still need to play many of the 2013 games before I can properly evaluate that year, but A Link Between Worlds alone makes it worth mentioning.
