The thing here is programming the job can be much more dull than programming the hobby. Occasionally (twice a decade) there can be a collision where you get to do something really cool like that at work. The higher ups want a realistic sky because their market research said it'll boost an OKR by 10 basis points. And then you are in luck!

That said there are niches where jobs let you do cool stuff all the time. Hard to find. Probably why gaming jobs are notoriously underpaid and overworked.
