Stardew Valley
Genre: Base Building
I've played the main story 1 time and given it an average score of 4 (out of 4).
This is a pretty fun game. It's relaxing, methodical, well animated and a charming. The story is light, but there's a lot to do. I didn't realize I had this many hours in it, but that's part of the fun. It's interesting to look back and think about what the "fun" of it was. My favorite part was growing and organizing crops. Seeing what is available for harvest in the morning is great. The wiki was invaluable, it would be nice to have some of that info more readily available in game. At some point it's like busywork, but it's wholesome relaxing busywork and there's definitely worse ways to spend time. One challenge is to not worry too much about min-maxing. It's not hard to do, but once you've done it, that's about it for the game. Also there's no official way to "beat" the game, but I'm making a lot of money and I did all the story quests.
