I love Stardew and played a bunch when it was first released.

He really had perfect timing with its release. The original developers and the rights holders for harvest moon had so badly fumbled for so long with bad releases or only in Japan releases etc. Someone was bound to show up in that space since there was a clear demand for that type of game. It also helps that he aped (heh) harvest moon from the super nintendo / game boy generation so it basically runs on a potato and no one needs to buy dedicated hardware.
