I was thinking it would be kool for nintendo to start a MMORPG based on the mushroom kingdom as shown in the rpg type mario games
Races could be like:
Classes could turn ur koopa trooper into like that little witch or a paratrooper. Give your boo king boo status. Turn ur Toad into an enginer that makes spaceships. Make your yoshi be able to carry a party members and get wings. And they could finaly explore and get deeper into Shyguys.
You could get weapons and equipment like FLUUD and the Poltergust 3000 and explore from the dry dry desert to delfino island
The Story kould chronicle a time wear key players like Mario, Luigi, Peach, and bowser are no where to be found and the kingdom is lost in confusion.
