Mega corp
>plot
Mega corp has driven up prices of items. "Natural" items like berries and herbs are sold by "black market" people. Poke balls are also expensive so apricorn balls cal be readily produced by non corporation people. Trainer goes through the league thinking the corp is good. Rival is the child of the corp leader and your childhood friend. Cover mascots could represent greed and charity.

Wider trainer customization, new fossils, more exploration, skippable cutscenes, less linear should you chose to branch from the suggested path.
That's my wishlist for a game
