Pilotwings 64, the second entry in Nintendo's flight sim series that began in 1991 on the Super NES, featured multiple islands to explore in a variety of aircraft. One island condensed many notable landmarks in the U.S. into an area called "Little States." There were a few changes, of course. The version of Mount Rushmore featured the smiling face of Mario, for example. Mischievous players who decided to fire a projectile at the plumber's face were surprised to discover that it transformed into an image of his nemesis, Wario.
