Splatoon is definitely the sort of game parents would buy for their young children, Zombi U and Bayonetta 2 definitely isn't.
Splatoon is clearly a fantastic fit for the wii u audience and fits in well with all the other wii u games that have sold 2 million plus (kart, smash, nintendoland, mario bros u, luigi and mario 3d. )
I think when Zombi U was developed there was still hope that the wii u would appeal to a wider audience but at this point its clear it has utterly failed to do so so development should be towards existing wii u owners who perhaps like me have bought a Nintendo console for mainly Nintendo's own exclusives and the few other decent exclusives. The wii u hardware is incredibly limiting so not much point trying to compete with ps4 and xbone head on with multiformat titles.
