>>34768393 says.
In fact I would straight out combine Kanto and Johto into one massive region with players choice where to start. Make it so you have to earn 10 badges to get to the league. All gyms are still in place and there is some other perk for obtaining all 16 badges. I would exclude some Pokémon from gen 2 just so that yhe dev team could maintain balance and not over extend the teams work load. New types like dark and fairy should continue to exist for balance reasons so they would include Hounddoom and Tyranitar as well as Snubbull as a fairy type. Baby lines would also exist and be available in the Wild and not just available from hatching from an egg.
