Pokemon's map design and combat mechanics are very abstract and leave a lot to the imagination, so Pokemon players fill in the gaps using their imagination. The small towns and cities become realistically sized ones with real-life infrastructure, and a turn-based battle becomes this epic anime style fight. They're just barebones enough to allow the player to imagine something grander than Game Freak ever design or program.
