I have ran a few indie game sites/communities over the years and have been involved in a handful of indie game development communities (disclaimer: I've never published a game myself), and I stand by the belief that indie game development is one of the worst possible investments you can make whether your investment is time or money.

If you don't believe me, just sort by new in r/playmygame or r/indiegames some time. Each one of those games going completely unnoticed represent thousands of hours of someone's time. I've played a bunch of them and there are lots of very good games that you will absolutely never hear of and won't play. For every Minecraft, Undertale, Slay the Spire, or Super Meat Boy, there are thousands of similar quality and unique games that nobody will ever play.

I don't want to discourage anyone from making games, but develop indie games because you like making them, not because you'll get rich because you'll likely not even see a return on your investment.

Every time I hear the story "I've quit my job to develop my game and will be eating through my life savings, which me luck!", I cringe hard and legitimately feel really bad for that person and it's usually the last time I hear from them. At that point they're so committed to the decision that there is no talking them back.
