For me it’s per activity and how you get your fun from it.
Like for example, in a game of hide and seek, the fun part is exploring and finding where people hid, if you already know that then it is not fun anymore. This kind of activity lines the same as with reading books or watching a movie.
On cooking, it is a different kind of fun because the more you know, the more you can apply. Medicine people have the same tendencies as well as athletes for these.
There’s also the type of fun you get with jokes, or for music.
Other people’s mileage may vary as each have their own approaches to different activities.
prioritization is key. (at least for me)
I understand that some days I go down that hole so I set aside “play money” for play things.
poor students, adults, and working peeps need play time too. treat yourself day is counted as play time. knowing when play time is - that’s adulting.
the last thing I bought in this category is kimchi. never had it in kitchen form before so it was both a tasting and meal-pairing experience.
