Not every developer is trying to make a million dollar hit. Many have jobs that make pursuing games as a full-time thing impractical.

Game jams like Ludum Dare (http://www.ludumdare.com/compo/) show that there are a lot of people making games.

What I mean is there are some developers where if they make any money at all, it's a bonus. They're not in it for the money, and they're not doing it as a business.

For every developer that's serious and financially committed to making games there has to be at least a hundred that are far more casual.
