You start your adventure in the big resort hotel, apparently they want this hotel to serve as an MMO lobby, where you can see other players, interact with them, have quest boards, etc.
GF wants to set the start of the Adventure in a big tourist city instead of small towns.

Not just the Caves, they ideally want to randomly generate new Islands environments, so the region is technically infinite and costantly morphing.
Thus the Infinity Theme.
All Pokémon in Winds & Waves are either touchable/interactable or Ride Pokémon.
