I translated the latest Meisaku Album at Sega's website (I thought they discontinued this very informative series) which is an interview w/ Treasure CEO, talking about Gunstar Heroes. He tells some interesting stories about how they got Treasure off the ground, and finally a comment from a developer on why US versions of games back then were harder. I seem to recall debating w/ GSL a while back on whether Sega could make a Gunstar sequel w/o Treasure. It appears not based on this article.
