> FULL customization of the character.I want to be able to customize my character from a Lass to a Hiker and use that avatar online.
> Online mode with great replay value.Decent online modes (be creative, GF! small championship modes, battle-royale or whatever) that make it fun for a casual gameplay against other people without having to grind 100 hours for eggs first. And some way to customize on the fly your EVs / IVs / Nature for Online Battles, once you beaten the game. They could also revive the Secret Base system and make it actually interesting and evolved, the Switch is perfect for that.
> Characters and LocationsInteresting new characters and waifus, memorable locations to explore, and returning character cameos.
