What's a single player PC game you can't get enough of?

Just picked this one up yesterday and I’ve totally been hooked. Reminds me of stardew valley mixed with subnautica.

I put over 30 hours into this game and ended up not recommending it on steam.

Weird progression in that game. The sushi segments just turned into me cleaning dishes and grating wasabi...and I thought the entire sea people quest was bland... Also, Nexon is a pretty crap company but that's not so much a comment about the game. Another comment about the game is the forced fetishizing of shark murder. It made me deliver a shark head to a customer on a plate and watch them cry from happiness while they ate it. STOP MURDERING SHARKS???
