Region is called Kanto, and is located right next to Johto, Johto is available in the post game. Starters are Bulbasaur, a grass frog/dinosaur, Charmander, a fire lizard, and Squirtle, a water turtle. From what I've seen its extremely bare bones, but has around 140-150 in the regional dex. Designs are the worst since gen 1 (Galar if anybody forgot) and no new regional forms. Story's as basic as you can get, obtain 8 badges complete the dex blah blah blah you know the drill. Thats all I know for now.
