Because all of those things you listed are about passive consumption. Games are active consumption: they have you actively participate in them.

What happens in movies, books, sports games, etc. are determined by others. You simply watch. In games however the outcome is tied (sometimes directly, sometimes indirectly) to your own actions. That's why they can be addicting, especially for people who otherwise feel like they don't have any agency in "real life."

If someone manages to make the means of production available and easy to use, as fulfilling as games... Things could change.

Games are like drugs in a sense because they provide the high of achievement easily with much less work than actual work.

Although people do like to partially build things as IKEA shows.

Books are as interactive as you make them.

I read a book by looking at contents, notes, bibliography, and index. Then the intro and conclusion. If the meat is worth reading, that.

This means reading for information rather than pleasure, for the most part, though for me, reading for information is pleasure. Yes, there's some fiction I'll read, but that's different.

There's also note-taking and organising my own thoughts as a consequence of what I'm reading.

I like what you're saying, but let's get real. The people playing games are looking for a different kind of feeling.
