Custom Maid 3d 2
Splatoon
etc

Let's see... In no particular order:

Captain Toad
Mother 3
Splatoon
Shovel Knight
Ori and the Blind Forest
Monster Hunter 4
Dragon Age: Inquisition
Batman: Arkham Knight
Kirby and the Rainbow Paintbrush
Shin Megami Tensei IV
Tomb Raider (360 reboot)
Gears of War: Judgement


In addition to that I replayed Knights of the Old Republic (Xbox) and Baten Kaitos for the first time in years, Advance Wars 1 + 2 on Virtual Console, and I've been playing Smash Bros and Mario Kart 8 on Wii U. I've not counted Majora's Mask 3D because I'd played the original. I need to finish Kirby and Dragon Age, then I have EarthBound: Beginnings (thinking of doing a Mother trilogy playthrough), Tengami, Golden Sun: The Lost Age (VC), DK64 (VC), Game of Thrones and Witcher 3 to play on Wii U and Xbox One.

Rare Replay is on the way, too. After that I'll want Destiny: Taken King, Mario Maker, Star Fox Zero, Xenoblade X, Fallout 4, Halo 5, and maybe Mario Tennis and Triforce Heroes.
