The Wii takes second place for me.
From Nintendo's own greats like Mario Galaxy 1 and 2, Xenoblade, Metroid Prime 3, Donkey Kong Country Returns, Twilight Princess, and Skyward Sword to third party developed titles like Monster Hunter Tri, The Last Story, Sin & Punishment 2, Fatal Frame 4, Fatal Frame 2 reimagining, No More Heroes 1 & 2, Goldeneye 007 remake, COD Modern Warfare/World at War/Black Ops/Modern Warfare 3, etc, its lineup is second only to the SNES in my book.
Plus motion controls were such a fresh and cool innovation that rekindled an excitement I hadn't felt since the leap to 3D in the 5th generation, and really enhanced gameplay when well implemented.
