History Main / DualWorldGameplay

* MarioParty has a few boards that change state. All of the boards in MarioParty 6 undergo a day/night cycle.

*** ''VideoGame/SuperMarioBros3'' has a similar island, where going through doors shrinks the normally enormous enemies to normal size. The environment remains big, however.

* ''WarioLand 3'' has a day/night cycle integrated into the entire game, with each level mapped twice for day and night. [[GuideDangIt Many treasures cannot be accessed at the wrong time.]] During the day, [[{{Mooks}} monsters patrol everywhere]] and doors in cities are open. At night, [[MechaMooks robots prowl where enemies were]], and the hungry dead stalk the dark places. Near the end of the game, you get an item that lets you change the time of day on the world map without having to enter a level.

* ''MarioAndLuigiPartnersInTime'' is a disappointing subversion. Although the plot revolves around time travel, you don't actually get to explore any of the Mushroom Kingdom in the present. The only time Dual World Gameplay comes up is in TheVeryDefinitelyFinalDungeon, where the only way you know where you're going is because [[TheHub you've been through the Castle a few dozen times in the present]].

*** ''SuperMarioBros3'' has a similar island, where going through doors shrinks the normally enormous enemies to normal size. The environment remains big, however.

** Happens strangely in ''[[{{ptitlepf9wvkpu}} Bowser's Inside Story]]''. In some places, Bowser can do things that change some aspects of his internal workings. If he drinks water, some areas become covered in such, allowing the Bros to swim. Standing in front of an X-ray reveals some passages. And so on.

** ''SuperMarioBros2'' has the magic potion, which makes a door to a DarkWorld where you can grab coins and power-ups. You were only limited to the screen you made the door on, so the trick is to find places where powerups are hidden and make the door there.

If only a single level in a game uses this, it's a MirrorWorld or DarkWorld.

** ''SuperMario64'' features Tiny/Huge Island, where Mario can go through pipes to change size. As a giant, Mario can easily jump up cliffs and doesn't need to worry much about enemies. As a midget, Mario can ride on breezes and enter narrow passages. This is implemented by two different maps of the same island.

* ''DayOfTheTentacle'' features a novel variation. The three characters are trapped in three different time periods and have to work together, [[BagOfSharing using items from different time periods]] [[JustifiedTrope by passing them through]] [[NotMakingThisUpDisclaimer a time-traveling toilet]].

** The companion game, OracleOfSeasons, features season-changing gameplay. Every part of the world map is mapped differently for each of the four seasons. Spring makes big flowers grow that shoot you up cliffs, water dries up and vines grow up walls in the summer, leaves cover pits and mushrooms soften in the fall, and water freezes in the winter.

* ''{{Minecraft}}'' has the normal world and [[FireAndBrimstoneHell the Nether]], accessible through [[spoiler: obsidian portals when lit on fire.]] (This is creates an inconvenience in SMP - survival mode multi-player - where having two maps hosted on the same server can be a major memory strain.) The Nether is smaller than the normal world, ten meters in the Nether is a hundred meters outside. This makes it convenient for fast travel, [[EverythingTryingToKillYou assuming you can travel safely]].

** Happens strangely in ''[[{{ptitlepf9wvkpu}} Bowser's Inside Story]]'', as you not only switch between worlds, but between ''characters'' as well.

* Enemies only appear in one of the worlds ([[EverythingIsTryingToKillYou demons only occur in the demon world]], roaming zombies only happen after the ZombieApocalypse)

* Having a particular transition point or points to prevent the player from changing too freely (a PortalBetweenTheWorlds, a time machine)

* ''MetroidPrime 2: Echoes'' has Samus travel between Aether and Dark Aether. The planet was split by [[spoiler:the impact of a Phazon meteor,]] and the inhabitants of Dark Aether started an invasion. [[ItGotWorse Even worse,]] [[ApocalypseHow Aether is in danger of being destroyed]] because the Ing stole critical technology from the native Luminoth. [[LateToTheParty Samus finds portals made by the Luminoth]] that let her travel there to set things right. Because Dark Aether isn't as interconnected, each level's DarkWorld [[HighOctaneNightmareFuel feels like a claustrophobic, twisted splinter of reality]].

* Mario&Luigi: Partners in Time is a disappointing subversion. Although the plot revolves around time travel, you don't actually get to explore any of the Mushroom Kingdom in the present.

** Super Mario Bros 2 (subcon) has the magic potion, which makes a door to a DarkWorld where you can grab coins and power-ups. You were only limited to the screen you made the door on, so the trick is to find places where powerups are hidden and make the door there.
** Mario64 features Tiny/Huge Island, where mario can go through pipes to change size. As a giant, Mario can easily jump up cliffs and doesn't need to worry much about enemies. As a midget, mario can ride on breezes and enter narrow passages. This is implemented by two different maps of the same island.

** Four Swords Adventures also featuerd the Dark World, but it didn't cover the entire world. Link could collect Moon Pearls in some levels to open portals, which were used to bypass obstacles and solve puzzles. It came up fairly often, but it wasn't central to the game.

** Mario64 features Tiny/Big Island, where mario can go through pipes to change size. As a giant, Mario can easily jump up cliffs and doesn't need to worry much about enemies. As a midget, mario can ride on breezes and enter narrow passages. This is implemented by two different maps of the same island.
