Why stardew valley is so addictive?

I think, in my opinion that Stardew is so addictive, is because of its wide range of possibilities you can do.

Like how much creativity you can add to the game, and your farm and how much deep lore there is. And the crazy mods that can be added too.

These are what make the game so fun, for something so relaxing. 

This picture is one of the many possiblities of the game.
