2D Sprite based again (similar to Gen 5 visually), call it some Celebration of the series or whatever to make people who are obsessed with 3D get on board.
Every single Pokemon in the game. Every single Pokemon catchable. ALL OF THEM. Lock mythicals/legends behind Post game content
Megas back, literally the only good gimmick since they've started adding gimmicks
Gyms can be done in any order, and have different teams based on how many badges you have.
Hard mode - all enemy trainer Pokemon have held items, all have EVs, competitive movesets etc (few in early game, more as you progress)
item limit in combat.
level limits: Pokemon stop gaining XP at a level threshold until next gym badge earned
More double battles
Robust post game content
2 full regions.
Gym leader rematches.
Keep the cooking mechanics, but have actual food buffs for Pokemon. Increased XP food, and other such effects.
Gamefreak will never do any of this and will continue to put out low effort content because it will sell anyway.
