My issue is not with you asking for advice. My issue is with the way you dismiss the other things, and try to rationalize your
preference as something ethically/morally superior.
You started the post making sweeping generalizations about things that you don't like but pay well, then you go to complain about companies that may as well be profitable and a good place to work on the grounds of "not having best practices".
So, what is going to satisfy you... Oh, yes, let's see what you want to do: it's not even a game, but actually you want to bring to the world another game engine... Hippity dickity yawn, that is only interesting for the overgrown children whose only issue in their lives is their total lack of social skills.
You were asking for advice, so here is mine: if every job is so boring to you and yet you don't feel like you have what it takes to be in charge of your own professional life, accept that this is a "you" problem, not a "them" problem. If every job you had is "uninteresting", perhaps your focus should be in developing other skills that can let you see the interesting challenges that exist in every industry.
