Personal wishlist:
Exp. All- If it will still be a broken mess, which I can't deny comes in handy, then they should go Gen 1 route in which it was obtained mid game and it was locked behind a 45 (?) captured Pokemon requirement. This would invite people to catch more Pokemon if they want to break the game so bad, and at mid game so the beginning is as frustrating and grindy as the good old Pokemon games. And if they want lame grinding back so bad bring back Audino grinding from Gen 5, which was handy but tedious.
Customization- Please let us remove the hat. I saw a video showing it MIGHT be possible, but I want this confirmed. Let us buy outfits from the other protagonists of the Pokemon games, and for giggles the previous evil team uniforms. Let us have crazy hair colors like blue or white. If the NPCs can why can't us?
Get over event exclusive Pokemon- It will baffle me if GameFreak leaves 3 legendaries hidden that will be discovered by hackers day 1, and release them on completely arbitrary dates and locations by the time I already dropped the game. Seriously, it's predictable and annoying. Integrate this crittens somewhere in the game, like I don't know, post game!? One of the main flaws with this games and where Gen 6 failed? And I'm not only talking Gen 7, I am talking about all of those devilish event Pokemon (Mew, Celebi, Jirachi, Manaphy, Darkrai, Shaymin, Arceus, Victini, Keldeo, Meloetta, Genesect, Diancie, Hoopa, Volcanion). Seriously, screw event exclusives. It is an inconsistent and biased system (ex. Jirachi is almost NEVER given away in America, and in Japan they give them out like candy, the stupid region exclusive events) to piss on completionists. They integrated Deoxys in ORAS just fine, as well as shoehorning every other legendary in there as well. If they could with them, they can with everyone. And if they want the process to be ridiculous and complicated like the Mew gltich then fine, just let me catch this devils and end my misery!
Let HMs be forgettable- Plz.
