The Hoenn region was so damn kino that Game Freak tried to do it AGAIN the very next generation. The Battle Zone in Sinnoh is literally just diet-Hoenn; you have your water routes, mountainous routes, desert area, volcanic area and a boatload of Hoenn mons to boot. They had such little faith in Sinnoh as its own standalone region that they included a homage to Hoenn even though it doesn't make geographical sense. Holy kek, Hoennsisters are on top
