Part of me would like to do that. But part of me is also very consciously aware I'm terrible at self-managing / motivating, and that the indie game development market is flooded by people and games that are a lot more creative than the ones I could come up with who still aren't able to make ends meet years down the line.

But maybe I'm just cynical and afraid to get out of my comfort zone.

If you were doing it just for fun, with no expectation of a financial or reputational payoff, would you still like to do it? Would it feel different?

Yes, but I (we? I get the feeling I’m not alone in this...) never finish them. It’s always more fun to start the next one than finish the first.
