Nintendo needs to wise up. Their traditional core franchises don't have as much relevance as they used to. If they were smart, they would have waited. Imagine if the Wii U had launched with X and Super Mario 3D World. And while we're at it, let's call the system the Wii 2 to avoid consumer confusion. Instead, we've had a full year with next to no notable releases other than Monster Hunter 3 Ultimate and Wind Waker HD. Good games, but nothing really new or much of a system seller. There's also plenty of interesting IPs that Nintendo could bring back. Mach Rider, Custom Robo, Mother, Wario, Metroid, F-Zero, Golden Sun. Give people a reason to buy the Wii U, beyond Mario and Zelda. And for fuck's sake stop region locking games. If Capcom or whomever refuses to localize a title, on a Playstation system, at least I have the option of importing it.
So, should Nintendo seriously listen to every little thing consumers have to say? No.
But they should take note of trends, and pay attention to when certain things are voiced on a large scale.
