>>19017246I remember being a kid, and enjoying the underground purely because it gave me such quick cash.
Not to mention, it allowed one the ability to construct a secret base like Gen III.
I wish that they would bring it back, especially something like a combination of renting a house or something, and decorating it to your desires.
Maybe even have that you can unlock certain extras that benefit you in-game.
Like an ST-Gym or a small window garden for berry bushes.
Maybe be able to stock up on berries that you can use in a blender to provide drinks to your pokemon.
Or make specialized food for them that boosts their stats.
