Really excited to see what they do with Super Hot. Mario Maker is what I am most excited for on that list. It just has so much potential to be an incredible game with infinite replay-ability. As long as they do right with the different game physics and let you make some real crazy ass shit and have a serviceable online structure, then count me the fuck in.
Actually, fuck that. I completely missed Splatoon. Splatoon has a chance of being something really special. I remember watching that first announcement trailer at E3 a couple years ago and I just fucking GOT it was going for and I loved it. They're just showing lots of neat ways they can fuck around with the gameplay system built for this shooter.
They've shown off some single player stuff recently and I wasn't completely sold with that they've shown. I wouldn't mind if Nintendo was able to pull of a strictly multiplayer only shooter with a some sort of online system in place. I love the style, love the music and I can already tell the gameplay is going to be fucking terrific. Deliver on the online multiplayer experience and maybe add some sort of leveling up mechanic and they'll have another great franchise in their hands.
