Last I checked, Goodman Games has.
I'm sure Joe is flattered you think his business is comparable to GR.
Goodman does have an great business plan that breaks many conventions of thought, is has a solid degree of success because of it, but Goodman Games is till no Green Ronin, and has no where near the same business concerns GR has to consider when it comes to the GSL and 4E. Hence, Goodmans ability to do it, when GR doesn't. A comparison of GR and Paizo is much more appropriate, but there are still a couple of magnitudes of difference between even these two, but they have far more in common with regards to doing the GSL or not, and they made similar decisions because of these similarities.
Plus I think both Paizo and GR, and Goodman for that matter, are successful business' because they are capable of removing personal feelings from their decision making when its time to make their decisions. Besides, it is a no brainer to not have done the GSL and 4E when you look at the assets GR has. Same is now obviously true of Paizo, who has also done several "outside the box" business decisions. Staying 3E being one of the first, and giving away their Alpha and Beta Rules PDF's for free being more examples. There were, and still are, plenty of people thinking their decisions are crazy, but they still seem to be pretty darn successful because of their insane decisions.
Paizo will know for sure come August of 2010 just how insane, or brilliant, they were. Its certainly seeming brilliant right now.
