All of these successes you named happened before the so called "indiepocalypse" and are the result of a decade of experience prior or from the project itself. This is survivorship bias. Success takes time, resilience, discipline, talent and a lot of luck but even then you'll still probably lose. Look, the vast majority of people fail to become marketable artists, musicians, writers, engineers.. why do you feel the need to claim that a task combining all of the above and more is "not that hard"? It's unrealistic. I encourage everyone that has the desire to do it and to support each other but never to lie to themselves and distort reality as a coping mechanism.. this path is a long road littered with the corpses of past failures. Most people don't find it fun (which is why they quit) and even those that do wouldn't dare to claim it's fun most of the time. Rewarding might be a better term but only if you can appreciate self growth more than materialistic rewards.. because even in success gatekeepers take a large cut of your usually small earnings, the audience loves you as much as they hate you while the rest of the world either doesn't get it or wants to use you. Dramatic? Yes lol. But am I wrong? No. This is how you present it. You still want to be a game dev after hearing that? Go for it you crazy mother fucker :D
