Jobs are trade offs. You get to choose which one you take.
If you love making video games and one video game company has worse working conditions than all the others, quit that one and go work for one of the other ones.
If you love making video games and all the video game companies have poor working conditions because too many people love making video games and therefore the market is saturated, this a thing that only you can do anything about. The company you work for is already trying to maximize profits in a competitive market. To improve your working conditions they'd have to make more money, but if they could do that so easily they'd have done it already.
You, by contrast, have an actual choice. Do you love this job, working conditions and all, better than your other available alternatives? If the answer is yes, you've made your choice. But for some people the answer is going to be no, and it's those people, choosing something else, that establish the floor for working conditions. They can only go as low as you're willing to put up with. So don't put up with less than you find reasonable.
It's the thing that creates change. Less people are willing to do the job, so less video games get made, competition is less aggressive so each company makes more revenue which allows working conditions to improve. Other solutions will have results no better than this and most of them are just roundabout ways to achieve the equivalent result with higher transaction costs or some kind of perfidious rent seeking or gatekeeping.
The real "problem" is that people want fun and interesting jobs that everybody wants to pay as much as dull and dirty jobs that nobody wants, but that's not how it works. At the same skill level, the shittier job pays better. Because if it doesn't, you quit.
