Unrevisitable area

Unrevisitable locations are locations in Mario games that are inaccessible after a certain point. Unrevisitable locations are primarily found in Mario RPGs where the player is automatically taken to such locations during the storyline and may contain items or accessories that can be missed. Some platformer games that allow the player to roam on world maps may contain stages that can only be accessed once on the world map, or near the beginning of the game.

Due to the nature of linear games such as Super Mario Bros., they are not listed on this page.
