It seems to me that if you're not contracted to a publisher, you are going to have to cut corners on development costs and write a low profit game, though. I don't think too many of them are in it for the money. The nice thing is there is more area for this type of developer. With digital distribution, web games, etc, it has cut the costs of development way down for smaller games. It's pretty cut throat I think, though, because there are so many trying to do it. I wouldn't want to do it, myself. I think it's kind of a fun hobby, but I don't think I would want to have to pay the bills on it. It's not reliable income.
