Mario Game Ideas?

It hasn't - fans say they're brothers just like M&L but it's never been confirmed (that would be another thing this game could expand upon)
 
I think they're brothers because in Mario Party 5, if they teamed up, They're called Wario Bros.
 
Why not? The Mario Party series may be garbage, but that game is still an official source.
 
Nintendo definately needs to put Waluigi (as well as other characters such as Wario and Daisy) in the main series games. I'd also personally love a deeper storyline (Not Final Fantasy deep, but at least something else other than saving Princess Peach.) I would also love a main antagonist other than Bowser. Fawful maybe? (Oh lord, that would be sweet.)

Oh, and you know what i would love? "Mario House Party"
Over 80 minigames including "Beer pong panic", "Drunk kart kraziness", and "Bail like Bowser"
 
Wario has his own series, and Daisy wouldn't be of much help if the plot is to kidnap Peach, IMO.

Also Waluigi is an atrocity of nature.
 
A thread for Mario game ideas? That's cool. I've always thought that a "Super Mario World DS" type-game would be awesome. You know, it would take place in Dinosaur Land, it would have the enemies from Super Mario World, that stuff. I loved the old SMW-- it was the first Mario game I owned-- but by now, it's pretty old. This new SMW DS game could have all the good old stuff from the original SMW (like all those cool places, definitely), and it could add some new elements (modern graphics, probably some new characters). It might be more like an RPG-style platformer, I guess.
Seriously, I would love that game. Does anyone else think that's a good idea?
