I absolutely agree with you hechelion. I am making - imo nicer looking - games for years beside my full time job in the field of engineering. Without having marketing - except e-mails to friends and family - I built a very modest following and I don't know how many would actually spend money to play my games. I personally don't want payments because among other things it would complicate my taxes more than it is worth.
And there is another aspect. I'd call it "the grass is always greener on the other side". There must be something that made DNA games become an engineer. But once he was an engineer he though game development would be nicer. Now that he is a game developer is guess he is already thinking of something that would be nicer... No job is 100% fun. Not even game development. I can still love my job even if I have to go through parts that aren't fun. I think it's quite satisfying to work with actual physical products.
