No gyms, instead something akin to the island-challenges of Sun/Moon, but more than a stupid minigame. More like environment-based puzzles that end in a challenging boss battle.
It would probably take some heavy inspiration from the Etrian Odyssey series regarding its gameplay.
The story would be rather simple, since it doesn't really require a evil human team - rather, the environment consisting of challenging routes and dungeons would be the enemy.
