Best Wii U game without Mario in it

[Skullwaker]

Wind Waker HD if we're including remasters, Splatoon if we're not.

It was really close call between them, Bayonetta 2 & Xenoblade Chronicles X, but WWHD is my favorite game ever and I've put nearly 300 hours into Splatoon, so those games have a bit more weight for me. xD
