I think that's changing a bit, though. There are a lot more independant developers and people who are skipping the mainstream publishing/dev-studio industry and finding better success. And if they're both irrational choices, why not?
Some examples: the game that swept the GDC Choice awards was Journey, made by a small independent studio with an exclusivity deal rather than a more traditional publishing relationship. Minecraft is one of the best-selling games of all time: the XBox 360 version alone sold more than Gears of War 2, to give you a point of comparison. The average indie game won't see this level of success, of course, but neither will the average big-publishing mainstream game.
