What would it be?

It could be single Pokemon ideas, or modes of travel, whatever. Let's say that anything you ask for [Within reason, those of you with dirty minds] will be thrown in the game, exactly how you want it to be done. What would it be?

Out of every idea I've thought of, I still want to travel to every Region in PokeEarth. I don't care how I get there. I just want to visit every city in Pokehistory, as well as be able to challenge EVERY trainer in the world, and destroy them with my crew.

For me its hard to go huge, but I personally want a truly realistic weather system: all kinds of weather (Rain, Snow, Hail, Thunderstorms, Tornadoes, Typhoons, Mist, Fog, Clouds, Heat Wave, etc.), easily affected in the field by your Pokémon, and all changing throughout the days and nights.

...But I'm weird

All I wish for is multiple save slots. I'd like all of the other mechanics and features to be preserved.

Maybe specific gender differences like colors of your room or something that may change the storyline whether you choose a boy or a girl???

A third elemental type, above all things. It opens up thousands of possibilities with movesets and Pokemon designs.

ie: Water/Ice/Flying type Pokemon

The ability to fully customise your character. And I don't just mean copy another trainer class' sprite, I mean create your own character with clothing options, maybe the ability to change your size. That way when you're battling online everyone doesn't look EXACTLY THE SAME

Me wants new saves!!
