“Nintendo not letting itself make a browser Mario game has not stopped a flash flood of in-browser Mario games. Super Mario Flash, New Super Mario Bros. Flash, Infinite Mario, and the amazing Super Mario Crossover, which lets you play the original SMB games using characters from Castlevania, Excitebike, Ninja Gaidan, and more. (If you like that, try Abobo's Big Adventure.) There are free (and unlicensed) Mario games where he rides a motorbike, takes a shotgun to the Mushroom Kingdom, decides to fight with his fists, is replaced by Sonic, replaces Pac-Man in a maze game, and plays dress-up. They receive no admonition from Nintendo's once-ferocious legal department. Why not? Iwata's explanation is commonsensical: "[I]t would not be appropriate if we treated people who did someone based on affection for Nintendo as criminals." This is also why no one has been told by lawyers to stop selling Wario-as-a-pimp T-shirts.”
