Super Mario Bros. 2 (USA)
Nintendo Entertainment System/Famicom

A sprite rip of the Japanese Game Doki Doki Panic, Super Mario Bros. 2 remains one of the most controversial and standout titles in the Super Mario series for this very reason.

The title was later released in Japan under the name "Super Mario USA".

In this game, players could choose Princess Peach (known as "Princess Toadstool" back then) as a playable character for the very first time, making use of her powerful ability to float in midair. This came at the sacrifice of low running speed and physical strength to lift up objects out of the ground quickly. Her floating and ability to pluck vegetables from the ground to throw at enemies later became part of her moveset in the Super Smash Bros. series.
