>>11139099% of indie games are not profitable in the sense that if you're in a first world country you would easily earn more working at McDonalds part-time. My guess is that over 90% of all indie games won't earn more than $5k total. There are tens of thousands of games released on Steam every year and that number has been climbing rapidly each year. Not every game is going to make it like Balatro, Vampire Survivors, Pizza Tower, etc. This guy makes $500/mo on Patreon plus $150/mo on YouTube. That's still a fraction what you'd make working at McDonalds part-time, but more than if you spent that time making an entire indie game. This is almost certainly just a side gig and hobby for this guy.
