When trying out my hand at designing a Pokémon region map, I wanted to know what other games’ region maps looked like. There wasn’t any single collection, so I’ve gathered the region maps from each generation here.
Kanto
The Kanto map from Generation I games is remarkable in how little detail there is: Land, water, routes, towns, interest points.The Kanto map from Generation III games adds terrain to the Gen I map.The Kanto map from Generation VII's Let's Go, Pikachu! and Let's Go, Eevee! keeps the stylized rectangular routes, but updates the terrain map with illustrations of buildings around the town markers.
Sevii Islands
The Sevii Islands map from Generation III games adds terrain to the Gen I map.
Johto
Generation II's map of Johto is perhaps less readable compared to the Gen I Kanto map: I can barely see the water route on the west of the map.Generation IV's Johto map shows the increased size of towns: some are as large as entire routes! Compared to the Generation II map, the distances between locations have changed as well as the map projection itself. The addition of mountainous terrain markers gives players some idea of the terrain in these areas.
Hoenn
Hoenn has a mix of water and land routes, and the routes where diving is possible are marked with a deeper blue.The inset town maps in the "Zoom View" are interesting in how little they convey: there are buildings here, and some of them are labeled, but there's no indication of roads or paths.
Sinnoh
Sinnoh ignores water routes, according to the map coloring. There are three plot-relevant lakes which overlay the routes, where other lakes underlay the route paths. Note that some routes are two blocks wide.The Pokétch's Berry Searcher App shows the same general map as the main overland map, but without terrain. Only routes and labeled areas are shown in this minimalist three-color image.The Generation VIII map of Sinnoh in Brilliant Diamond and Shining Pearl is a higher-fidelity version of the Generation IV map, yet incorporates stylized elements similar to the Galar map introduced in Generation VIII's Sword and Shield. From Generation IV, the routes are represented as a rectangular grid of orange blobs, connecting red or blue rounded rectangles depicting cities. The underlying geography of the Generation VIII map replaces a rough topographical map with a stylized outline of the islands, trimmed to straight lines and 45-degree angles and decorated with clip-art mountains and trees.Pokémon Legends: Arceus introduced more "open-world" elements, but with a lower-fidelity map. There are five regions that the player can travel to from the main village; there are no depicted routes to or from those regions.The fast-travel mechanism in the game is not described; it simply is.
Unova
Generation V's map for Unova is a radical departure from the rectangular route layouts of previous generations. The base map layer is artistically painted, showing details of biome and city that previous generations' maps did not. Routes are straight-ish orange lines, and cities become dots on the map. Points of interest are marked by green squares off the edge of routes, rather than being on the routes.
Kalos
In Generation VI, Kalos returns to a stylized terrain map of Generations I through IV, but keeps the stylized route lines of Generation V.
Alola
In Generation VII, Alola drops any sort of map markings entirely. All that's shown is satellite imagery of the islands.
Galar
Generation VIII gave up on trying to constrain the map to a single screen. The player can scroll the map freely. Towns are marked and illustrated, routes are numbered in the map, train routes are clearly depicted, and detailed terrain is given in the Wild Area section of the map. It looks kinda like a theme park map.
Paldea
Generation IX's Paldea in-game Rotom Phone map is a fine-detailed geographic map, where roads are defined by paths roughly drawn across the green grasses of the land. Specific terrains are defined by soil coloration, but there are no Routes as such. There are only Areas in this game. Image via Game8.Kitakami is its own secluded valley. Observe the drawn roadways, the cliffs, the waterways, the buildings: there are no defined Routes in this extension to Scarlet and Violet. Image via Game8.The Terarium at Blueberry Academy is a vast underwater facility in a paid DLC to Scarlet and Violet. Image via Game8.
Other notes
I’m skipping side games like Pokémon Ranger and Pokémon Colosseum because I’m not as familiar with their styles of exploration or gameplay. The same can be said for Mystery Dungeon, Pokopia, Snap, and Quest.
GO uses the map of our Earth already; it’s not worth commenting on.
Legends: A-Z doesn’t have a world map; it only has a map of a single city. That’s sufficiently different to warrant exclusion from this comparison.
