So with Yoshi's Woolly World done I guess I'll give Monster Hunter 3 a chance because going back to MK8 just feels monotonous and same goes for Splatoon. Yoshi's Woolly World is definitely a great platformer on the Wii U and can last up to 50hrs (I clocked this much) with all the hidden collectibles and such.
I clocked 29 hrs for completing it 100%. I even went back to get the remaining enemy statues. The only thing left is unlocking all amiibo Yoshis, but this will be done with amiiqo, I guess.
