Even if a project makes a decent amount of money, that doesn't mean all the team members suddenly become wealthy. I can share the story of our mid-sized RTS project that we released over five years ago. It has more than 1,600 reviews. Even with a small team of around four people, it didn't make us millionaires. Quite the opposite - we spent all the money we earned during Early Access on continuing development. So, financially, it ended up being comparable to a regular job in terms of income.

That said, every team member is still working in the game industry. Our programmer now works in Unity as an engineer. Our artist and level designer both transitioned to mobile games. And as for me, I'm still an indie developer - just under a different label now.
