So, you think nobody was interested in Twilight Princess? Metroid Prime Corruption? Super Smash Bros Brawl? Super Mario Galaxy?

Everyone excited in the forums went to buy their Wii and Wii Sports, a bundled game?

Way to dimiss the Nintendo IP's.

And a lot more than 3D World.

And, haven't you said that MK8 and SSBU didn't change the situation? Then people didn't go to buy a Wii U, more like the same already established userbase.

Being realistic? Yes it was Wii Sports. Its not to dimiss Nintendo's IPs, its just to say Wii Sports was that big.

Good. Then Nintendo don't need to focus on 3D World. He should have developed a real Wii Sports game.

First-party software and accessory sales brought in more than $190 million on their own. The Legend of Zelda: Twilight Princess in particular rang up strong sales of more than 454,000, or three games for every four consoles.

Metroid Prime 3 didn't do shit for the Wii either, lol. Just a shade over 1 million despite being released at the height of the Wii's popularity is actually fairly disappointing.

Nintendo could've released a Mario Poops game about Mario on a toilet for 4 hours and had it sell 2-3 million+ early on in the Wii cycle.

Everyone was hot on Wii Sports, and having some Mario was like having some pie for desert, everyone likes pie for desert, but don't get it twisted ... Wii Sports is what got them into the restaurant. Wii Sports was the main course, Mario was the side dish. 

Good. You have prove my point then. Wii Sports (software), Wii Fit (software), Wii Play (software) sold all those consoles. Therefore, software sells consoles. Now, what happens when you don't have software that appeals?

Nintendo could make the greatest 3D Mario game ever ... Wii U sales would still be about the same. 

Arguably they made the greatest Mario Kart game ever for Wii U, and this is a franchise that historically has outsold Mario 3D games most times out ... and it hasn't done shit to save the Wii U from being a failure. 

The same 4-5 Nintendo IP aren't enough to save a console platform. Doesn't matter how good they are either. I think that much is now fairly well established. They can help, but they're not getting you past 25 million if you have nothing else to sell with. 

Making the greatest 3D Mario, the greatest MK, the greatest SSB, the greatest Metroid, the greatest Zelda, the greatest Fire Emblem, the greatest Paper Mario wouldn't have made the console sell better? Even if it's just 25M, a mark that seems so far to the Wii U?

Uh yeah, and? Point is neither of them reversed the downward trend in home consoles as no 3D Mario or any traditional Nintendo title ever has.

Wii U's are being sold everyday since it's release. NSMBU carried it until 3D World, then Kart n Smash came and they've all been helping keep the baseline where it is currently. I mean really now, for what other reason are Wii U's being bought for?

Super Mario 64 for the N64 did.
