I glanced over the interview, but couldn't find anything about the Houser Brothers... He just says Take Two copied the open world formula from Shenmue and made a lot of money off of it.
In part 1, he also says Shenmue changed Final Fantasy, which is a weird thing to say considering FF games follow their own formula since before Shenmue. Excluding FF15 which I think wasn't really revealed to be Open World by the time this interview came out (2010)
