>>32959098Bring back the PSS and Poké Miles, with both functioning in an identical manner to Gen 6.
The Festival plaza now uses Poké Miles and is no longer used for any Wi-Fi activities that do not specifically involve it.
Shops are now fixed, but can can be upgraded over time with tech-tree-like paths. You can also go to your friend's plazas and use their services, if you have any.
Occasionally real NPCs will stop by and challenge you for a battle there if you've beaten the game.
Shops are generally made more useful across the board.
