It depends on whether you make software for a living or for OSS. One does not preclude the other, even if one is rarer. Given my situation, as I had initially stated, I am part of the latter. Even still, were I the former, I still don't get why one would work "for free" basically, especially in terms of a game versus real life.

Even oss has users to satisfy.

If you’re building oss with no users, or just for yourself, you’re functionally doing something more like art than coding in terms of how you prioritize and execute.

You’re not playing Factorio for a living, are you? Supposedly we’re talking about your free time.

Here's to hoping things like Patreon and GitHub Sponsors make it more common. These platforms could truly change the way things are done in the software world. Given enough sponsors, I could quit my job and focus on free software every day.
