Developing indie games and working in the games industry in general is a terrible way to make money. I went to university with someone who is working for one of the big game studios. He get's around half what you would expect to get building enterprise applications and regularly works long hours. Not everything is about making money though, it was his dream to work in the games industry, he loves what he does and is happy doing it.

Or he could work for a decent enterprise shop and spend the excessive part of "long hours" executing his vision on his projects.
