People always mention the GW stores in defending the company. They close more and more of those every year. Also, read any account of what its like to walk into one.
"Why hasn't anyone surpased GW?" They havent, yet... They dont even have the number 2 game anymore, fantasy has been pushed to 3. Its coming.
FASA was just as big, with novels, TV shows, movies, video games, you name it. Where are they now?
