Ever play Terraria or Starbound? They're similar in concept to Stardew Valley, and they're pretty much endless.

Admittedly, I haven't played Starbound in a while. I bought it in 2014 on my Mac because my friends at school were playing it, and the devs have made a number of changes to it since then. It used to have no storyline, but now it does have a full story with lots of missions. You get a spaceship and you get to upgrade it so that you can fly to different planets/worlds that have different enemies and resources. You craft all sorts of things. You can also build houses, buildings, etc and move people in. It's pretty similar to Dragon Quest Builders, except in 2D pixel art rather than 3D.
