I played a demo of it at Target and it was pretty fun. Don't think I'll buy a Wii U for it, though.
Buy it for Splatoon, Mario 3D World, Wind Waker HD, Mario Kart 8, Smash Bros., Dankey Kang Tropical Freeze, Pikmin 3, and Captain Toad. Then in-between rounds of Splatoon and such, buy Super Mario Maker on 9/11.
By the way, you kiddos can find me on the Nintendo Network under the username KelCGrammer.
