Nintendo + Sega WOW = Skies of Arcadia 2

Nintendo + Sega + Artoon = Panzer Dragoon Saga 2

Nintendo + Sega = Jet Set Radio 2

Nintendo + Crystal Dynamics = Shadow Man 3

Nintendo + Bungie = New FPS IP

and... the most important of all

Square Enix for Super Mario RPG 2

I agree. But still They should team up with Sony and make Sony vs Nintendo for both the Wii and PS3. That would be AMAZING!!

All of Nintendo's teams should get together and expand on the Subspace Emissary from Brawl, but make it into an RPG. Players could choose one of three starting points with Mario, Link, and Samus, each with their own beginning world and they meet up later in the game to team up and take down some plot from Ganondorf and Bowser. They could visit other worlds Kingdom Hearts style to meet people like Donkey Kong, Kirby, Yoshi, Captain Falcon, Pit and several others whose worlds are being affected by Ganondorf and Bowser.

I don't know...I just want an epic RPG where my default three is a bad*** trio of Mario, Link, and Samus with cool Final Smashes (Limit Breaks) of Mario Finale, Link's Triforce Slash, and Samus's Zero Laser. Mario and Link don't have to talk (I don't think Mario's voice is RPG material and Link doesn't talk at all other than that which we don't speak of).

And that is the best idea I could come up with in ten minutes...yes, flame away...
