I am considering writing a short story centered around Mario's world with a GTA twist.
The first story would be called Super Mario Brothers: Mushroom City. The story would revolve around Luigi being assassinated by a group of shyguys during a drive by via go-carts. After being absent from the city for five years, Mario returns to the city to avenge his brothers murder.
The sequel story, simply titled SMB: Lost and Shelled and would involve Toad in a plot similar to that of GTA: Lost and Damned, but set in the Mario universe.
The third story would be titled SMB: The Ballad of Birdo. Yoshi, who in this story is a drug addicted lover of Birdo, is tasked with retrieving a gold coin that has been stolen by the villianous Wario.
