Only One Setting/Videogames

* The entirety of the first Danganronpa game takes place in Hope's Peak Academy.
* As will be stated below, the main Super Mario Bros. videogames take place entirely in the Mushroom Kingdom.
	+ Likewise, the Super Mario World cartoon takes place entirely in Dinosaur Land.
* *Pokémon* in video game form averts this for the most part, but as for the spin-off games:
	+ Averted in *Hey You! Pikachu!* and its sequel *Pokémon Channel*, especially the latter.
	+ In *My Pokémon Ranch*, the titular ranch is the only setting of said game.
	+ Averted in *Pokémon Mystery Dungeon*.
* *Doki Doki Literature Club*. The school where the literature club is located is the most prominent setting in the whole game. Unless you get to the point where there's no one else but Monika...
	+ You don't even have to walk into the school at all. Just get rid of Monika and Sayori will go insane.
* *Animal Crossing*:
	+ From the very moment you arrive in town, the Japan-only N64 version is set entirely in it, as swapping out Memory Paks simply was not possible for said version.
	+ The GameCube game (including the Japan-only updated version): again, provided you only have the one memory card for your town, it's set entirely in said town.
	+ In *Wild World*, the City is added as an attempt to avert this. This was kept in *City Folk*.
	+ *New Leaf* replaces the City with Main Street, which is technically playing this trope straight... in theory. But one can still visit another's town. "Dreams" do not count against this trope, though.
		- The *Welcome amiibo* update adds in a campground, which somewhat averts this.
	+ *New Horizons* is set entirely on a deserted island. You *can*, however, visit another's island, averting this as well.
* *Super Mario Bros.*, being set entirely in the Mushroom Kingdom aside, tends to avert this. Even during the 8-bit era, scenery can change.
	+ The *Mario & Sonic at the Olympic Games* spin-off games take place entirely at, well, the Olympics.
* *Sonic the Hedgehog*:
	+ Pre-*Adventure* games took place entirely on Mobius.
	+ In *Sonic Adventure*, most of the action takes place in the city.
		- Averted with its sequel *Sonic Adventure 2*, which requires space travel later on in the plot.
	+ Due to the first two seasons being based off *Adventure* and *Adventure 2*, not to mention the Metarex Saga requiring space travel, *Sonic X* averts this.
	+ The *Mario & Sonic at the Olympic Games* spin-off series; see its above entry.
	+ *Sonic Colors* takes place entirely at Eggman's Incredible Interstellar Amusement Park. Until the very last cutscene.
	+ Being a game with many references to the franchise's past 20 years, there's no doubt *Sonic Generations* *will* avert this.
	+ *Sonic Mania*, due to it being a retrospect of the classic Sonic games.
* This is the case with Yandere Simulator's debug builds, as they only take place in Ayano's hometown, but mostly Akademi High School or Yandere-chan's house.
* *Pac-Man*: The original game took place entirely on the exact same maze(s), up until level 256 changed things up by filling half the screen with unreadable garbage.
	+ *Pac-Land* and *Pac-Man 2: The New Adventures* take place entirely in Pac-Land, which is a very expansive country to begin with.
	+ Meanwhile, *Pac-Man World* was the first *Pac-Man* game to avert this trope entirely.
