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

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.
