In my universe, I make that (net even, not gross) in half a year with essentially zero responsibility for marketing, taxes, customer support, etc. - nobody can realistically steal my work and cut into my wages with it - far less stress - and I keep making that over and over again every 6 months without having to do anything really that new or different.

In comparison, a game that grossed $100k, which I have to pay self-employment taxes on, and perhaps app store fees out of that too, sounds awfully mediocre, at best.
