When someone let me borrow their Nintendo Switch for a while, I finished the main story of Pokémon Shining Pearl, and then I just assembled a team of six Eeveelutions and was running around with them in the PokéPark, it was so fun :D
It's unfortunate that I can only have six Pokémon at once, not nine, so I can't walk around with all the Eeveelutions...
(Though I honestly prefer the pixel art style of the older games over the 3D graphics style of Pokémon Shining Pearl...)
