Playable Bowser in Mario Party 10 is enough for me to get that game.
Mario Maker is basically Kaizo Mario Maker, which is awesome.
I want Xenoblade Chronicles X, since I did love that game. But I want to see some more gameplay first.
Smash Bros... What's left to say? Although I'm skeptical of how the Amiibo's 'learn to be good'.
Other games, like Shantae and Shovel Knight are all strawberries on the big Nintendo cake.
