List of New Super Mario Bros. 2 pre-release and unused content


 * As seen in the screenshot, the number of coins would originally have an "x" next to it, as in the original, but this is changed in the final version.
 * Nintendo considered this game to be called New Super Mario Bros. Gold, but due to some of the over 80 stages being said to stand on their own outside the coin theme of the game, the game was renamed to New Super Mario Bros. 2.
 * The overworld theme, which is an upgraded version of the NSMBW overworld theme, originally had a different upgrade.
