YouTube user MediocreJake posted a time-lapse video of his blocky creation that shows off the building of each town, city and route. Jake told Polygon that he started work on Johto in May, building in small chunks over the weekend. In all, he estimates that it took around 210 hours to plan create, plus an additional 25 hours to make videos for each step.
Last year, he created the region of Kanto.
"I have only built Kanto and Johto so far, but Johto was definitely the most challenging," he said. "The Kanto build was based off of a GameBoy Advance game (FireRed), so it was easy to copy the design of Kanto with the limited graphics the game had at the time into Minecraft. The Johto build was originally based off of the HeartGold game, which meant a lot more detail was needed seeing as it was a Nintendo DS game and was more graphically detailed.
"My build ended up being a sort of re-imagination of the HeartGold map, seeing as it was almost impossible to attain that sort of detail within Minecraft without mods."
According to his Twitter account, his next step is to build the Hoenn region from Pokémon Ruby, Sapphire and Emerald.
