The Legend of Zelda: Breath of the Wild is easily my most anticipated game. With that out of the way, I'm very excited for:
New Mario (Especially if it's like 64), Yooka-Laylee, A Hat in Time, Bit.Trip Runner 3, Finding Paradise (To the Moon sequel) and Dragon Quest XI.
Also the Crash Bandicoot trilogy remake, but I don't have a PS4 and I'm hoping it comes to other platforms so I can play it.
