>>29362366-Updated visuals, but without looking shitty like Pokken. Keep it in the same vein as the 3DS games, just better.
-Beautiful, atmospheric locations that take advantage of the better graphics. Even the best locations in Pokemon games feel kind of dead because of the graphical limitations. Areas as gorgeous as pic related are a must.
-A much larger region. On a console the region should be at least twice the size of Kalos, or be two regions(one new, one old?).
-Cities and towns that actually feel like cities and towns, rather than tiny shells that couldn't actually accommodate a population greater than 8.
-The ability to transfer pokemon from 3DS games to the Switch game/s.
-A large regional dex so new/returning players can experience a more representative range of Pokemon.
-A rebalancing of the types. Fairy and Water too stronk, but Ice, Bug and Grass are too weak.
-A return to new gens having 100+ new Pokemon, goddammit.
