I've got like 500 hours clocked across three platforms... I play a lot of stardew and other life sim/crafting games that after the initial objectives the game and enjoyment you get out of it really becomes what you make of it.
I always found that I enjoy the game most when I'm not playing like "I" am the farmer and when my farmer is more than just a cute sprite and a different name. (Step away from what you know works best and focus on what the character you made would actually do)
Example: I had one playthrough were I was playing a brewery farm making beer, ale and mead. Ended up marrying Shane and played through an entire scenario where my farmer basically burned all their kegs and became a jelly baron.
I guess what I'm suggesting is try adding more roleplay into it. Making yourself do silly tasks because "x fake thing" happened can be pretty fun. I think I'm gonna do a supersticous character next and decide on a few silly tasks that I'll need to complete if "x thing happens" (Everytime I see a rabbit I have to eat a cave carrot, ECT.)
