Add NPCs to the game that we can hire to do household chores such as cooking, turning lights on and off, cleaning, and keeping the house tidy.

I also think this feature would help players who don't have friends to play with, giving them "servants" in the house so the experience doesn't feel so empty and becomes more immersive in role-playing games.

Then, after two or three days (in-game, obviously), we would have to pay them to prevent them from leaving.

And the characters would have predetermined skins, but with a new pass that players could customize the NPCs to their liking.
