I worked as an Outsource Manager at a couple of game companies (in addition to working for many years as a game artist). I outsourced mostly art asset creation, mostly to cheaper countries. It was kind of bittersweet, since it was clear to me and the artists at our studio that we were outsourcing really enjoyable work, work that our internal artists would rather have done than spend some of their time reviewing the cool art stuff these outsource artists created. But doing this allowed the studio to make a bigger, better game than our limited size team could do on their own.
So basically, I disagree with your premise. There are many sorts of jobs, for many reasons.
Sure. He made many millions of dollars within the first couple years of releasing it. That’s why he can pretty much do whatever he wants, including continuing to work on the game without charging additional money for it. And of course, it keeps selling more copies, and will for many years to come, so he has tons of money continuing to flood in.
He certainly seems like a pretty grounded guy, and it’s nice that he tries to be cool about stuff, including not gouging the player base for more money. Being an individual has huge advantages compared to being a corporation, in some ways. A corporation would pretty much be obligated to maximize profit. He can just be pleased that he brings joy to millions of players, and has already made a fortune.
