Post how would your perfect Pokémon game be. That game that you know will never exist.

For me
Focus on exploration and traveling more than defeating an evil team.
Basically a gigantic postgame.

All known regions are included to explore.
Full National Dex.
Huge interaction with your mons, following pokémon, riding, camping, more Wild Areas, the return of seasons, swarms, safari zones, specific hour and day events
Underground, interaction with trees (headbutt, honey slather, hidden grottoes), secret bases, diving, soaring, non annoying HMs to open new areas, photographing, DexNav, rematches, master trainers, all past competitions, Battle Frontier, World Tournament, Maison, Constests and Super Contests, Pokéathlon, Pokéstar Studios, Joint Avenue, your personal mansion, achievement medals, many ways of traveling like surfing Alola style, train, boat, ferry, airplane...

I'd even pay for each separate region as a DLC quality addition in order to have the entire pokémon world in one place for an evergrowing "postgame", which is for me the actual game as I don't care for the "stories" they like force.
