There are a lot of things that require a lot of time investment on a regular basis to really be worth it or effective, so a lot of things feel kind of out-of-reach next to a full-time job. I guess I can see the perspective of people who want to do indie game development full-time, since then you could do that without it being at the expense of something else.
@NovaSquirrel Also for me, it is just not feasible to hold a job at a company, so doing indie dev stuff (or any other personal project) is honestly the only long term option.
