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.
