I believe that it is time for a new franchise from Nintendo this is my idea:

Two creatures called Aqualve (water like creature) and Magvern (fire like creature) are forced by Shalakira (shadow like creature) to find all of the 45 rare minerals on the planet. Aqualve and Magvern escape and discover the land of Raiscent a place where tranquillity reside. Shalakira combines his land of Dimakia with Raiscent. A new land known as Surolo is created. Aqualve and Magvern discover that these minerals can restore the land to normal so they venture out to discover them. Shalakira sends 9 creatures out to defeat them. Eventually you can explore Dimakia and Raiscent along with Surolo. After this point many secrets are revealed.

Do you like this idea and do you have any ideas of your own?

a new IP?

Flare. A little soul that must retrieve his body. During an experiment, the soul has been separated from the body and now Flare looks like a flame. The big baddy is called RolStoppable. XD

I also have dropped acid before, we have something in common.

Edit: Whoops, accidental post click. Your idea is hella better than anything I can come up with so run with it.

Okay, get this: You play as a rotund Italian plumber who must undertake a daunting adventure and overcome overwhelming odds to rescue a beautiful blonde princess...

What? No good?

Fine, then how about assuming the role of an androgynous elf-boy who must undertake a daunting journey and overcome overwhelming odds to rescue a beautiful blonde princess...

Huh? That's been done, too?

Alright, alright... so you're an anthropomorphic fox, right? And you command an interplanetary fighter squadron on a quest to overcome overwhelming odds and rescue a beautiful blonde princess...

Aw, forget it. I've got nothing.

A new evil villain wants to take over the world, but he hears a rumor about the Super Mario Brothers who will stop him. He goes to look for them to capture them. He finds Mario and Wario in the middle of an intense battle. He goes "Aha! The Mario Brothers!" and captures both of them.

Luigi shows up to save Mario and gets his ass kicked.

Waluigi shows up to save Wario and gets his ass kicked.

They realize that even though they're enemies, they must join forces to rescue their brothers. It's like a wacky buddy cop comedy platformer.

I give you... The Super Luigi Brothers.

The name alone sells it. And it's also an excuse to make Waluigi a canon character finally. They get different powers and you switch back and forth Donkey Kong Country-style, or play 2p co-op.

How do I give this idea to Nintendo?

The Ghost of RubangB , your idea is awesome .

I want a sandbox game where the main character is Waluigi and you must do little dirty trick to beat the evil guy.

Now we see why Rainbow Yoshi is flying in the sky with those Lumas.

Another franchise which gathers the all-stars from the company.

Hmmm

The Last Story or Xenoblade. lol ;)

To be honest, I would love to see Nintendo revive some of their cult classics, like Icarus.


And Nintendo has amazing family friendly games,

but to be brutally honest, I would love to see Nintendo head a mature franchise (something that no one would ever imagine Nintendo would do. Not Metroid, Im thinking something bloody and gory). And not dynamic slash either; nothing they've published, but rather something they internally develop.

Simply because once Miyamoto said he would never put blood in a game for the sake of it. But if a game was designed where it needed blood, I think it would be interesting to see the guy do something like that (kinda like Spielberg going mature with Munich)

Sandy Colonies.  A Sandbox style title were you're a sand person and explore giant sand castles, mold your own sand castle and fight seafish and collect stuff that washes up on shore.

I'm not very creative, am I?
