Soooo Johto and Sinnoh are canonically next to each other..
Why can't they make a multiregion epic adventure game, possibly with an altered version of Kanto too?
It would be something new in that Johto and Sinnoh have not been in the same game before but nostalgic in both the classic regions and connecting two regions in one game, as was done in GSC.
It would also kill two birds with one stone, both lets go johto and the DP remakes while giving some fresh stuff to the community
