All of them. Just imagine how well a system would sell with the following games...
Monster Hunter 4.1 million copies for MH4.
Poke'Mon 14.7 for X/Y
Super Mario 3D Land 10.73 million
New Super Mario Bros. 5-10 million every game.
Mario Kart 14 million
Splatoon 4.17 million (That's insane for a new IP!!!)
Animal Crossing 10 million
Super Smash Bros 14 million combined sales.
Super Mario Maker 3.18 million
Here's the thing. With the switch people don't have to buy a 3DS *just* for poke'mon and Monster Hunter anymore. They also don't have to buy a Wii U *just* for Splatoon or MK8. People who always liked Nintendo games but didn't want to drop 200-300 on a system for just one or two games, can now get four or five games they really like all on one system.
