Okay hear me out. What if there was a Pokemon game where some Pokemon weren't meant for battling. For example, bird Pokemon are only used for getting around, object Pokemon are used like everyday objects, and cat pokemon are pets. Klefki can be used to unlock different areas and Torchic can light up dark areas. These won't act like HMs but it'll be similar to PokeRider. In this game you can still battle with Pokemon, like Bisharp, Luxray, the Legendaries, etc. Also there's no cities or towns, instead there's fortresses. Each fortress inhabits a different Pokemon. You'll have to use your team to solve puzzels. There will also be the occasional NPC to heal your Pokemon or something.
