That Disney analogy is pretty flawed. They have produced and continue to produce a variety of adult features, from stuff like Pretty Woman to Lincoln to Con Air, quite possibly the single greatest film ever made. Disney offers a wide variety of films for audiences to choose from; they produce all-ages animated films to action packed Marvel features to award winning drama pieces all the same.But honestly, imo, when Nintendo was around the 80's, they were the family system. Same with the SNES, and N64. But people who grew up with Nintendo, wanted Nintendo to grow up with them, and that's just not gonna happen. That's like asking Disney to make a serial thriller movie or something. That's not who they are.
People don't want all Nintendo games to get dark and gritty and edgy - they just want a little more branching out from Nintendo. When people say they'd like to see more mature Nintendo games, I don't mean "mature" (Blood, breasts, and bawdy boasts); they're looking for mature, adult subject matters along with the usual Mario/Zelda/etc. affairs.
I think Sony does the best job in terms of providing variety. From Little Big Planet to Ratchet and Clank to Killzone to Infamous and stuff like The Last of Us, Sony has consistently provided titles with a wide range of appeal without ever losing sense of itself. There's something for just about everyone in its lineup. I think Nintendo could take a few pointers from that.
The Wii U sells just fine at my Walmart I work at, so these "poor sales numbers" are bullshit at best.
Yes, your personal, isolated anecdote clearly accounts for all sales data across the world. Sales reports are just a conspiracy made to keep Nintendo down, man.
