Most hobbies are fake accomplishments, some things are just about joy. It's always about moderation
Isn't everything a fake accomplishment? If I like baking cakes does it mean I accomplished something by doing so? And conversely if I'm a runner does it mean it's fake because I'll never beat the world record?
When you say that, the example that pops into my mind is Stardew Valley. It's very satisfying as an escape because it provides periodic rewards while abstracting away nearly all potential sources of frustration. I'd be a little concerned about spending too much time immersed in that in a way that wouldn't bother me so much about other hobbies.
We're all giving our lives up to something. Do you really want to give your life away to hollow fake accomplishment?
