I'm some cases the games may not be as good, or may be overrated etc... depending on your tastes...
But actually Unlike Sony, Nintendo have the money to take risks on new IP's, and yet they're the ones not doing so. A new IP every other year wouldn't hurt! They must have enough ideas!... that seem to end up in their classic franchises instead, like Kirby's/Yoshi's Epic yarn etc...
Aside from games they've published, their First Party efforts have all been casual titles.
The Wii U was supposed to be bringing back the hardcore. Their words not mine.
