If Unova is remade what changes should be made so that it's not the poorest selling generation with the weakest cultural impact and legacy again?

At a bare minimum the entire region's encounter tables will need to be fixed to include as many Pokemon from the other gens as possible while keeping the actual Unovadex to a minimum. This will make it feel like an actual Pokemon game for the first time rather than some weird British fan fiction.

The regions should also be repurposed from the ground up to be much less linear and the annoying rival characters should be scrapped for better ones or way less in your face.
