You can also play video games that teach you things which are marginally useful in your life e.g. Paradox Grand Strategy titles (History) or games like Factorio (Systems design / "Programming") or even TIS-100 (actual programming)

Funny enough, I spent a few weeks binging on a somewhat realistic civil war sim called "Ultimate General: Civil War" which I think teaches (civil war era) military tactics and military history quite effectively. I now know all of the famous civil war battles pretty well.
