I remember even as a young boy feeling jipped exploring kanto in my silver version. Im sorry a bug catcher with a lvl 56 venomoth and lv.58 butterfree right outside the protagonists starting route from 3 years before, the same route where if you encountered a lvl6 pidgey it was luck but a couple years later you walts in and every ones pokemon league ready??
It ruins it.
If you ask me it should be one region, a large region with more free roam and sidequest
