PlayDevil recently had the chance to play a near final Saint's Row IV, and chat to one of the producers:
Here is a snippet:
"Saint’s Row 3 really brought Volition’s open world series into the big-time. Always more bombastic and crass than GTA, SR3 ratcheted the stupid up to 11, and was all the better for it. Now, with "Saints Row IV" just a month away, we had chance to play about with a basically final build to see what idiocy the developers have added over the last couple of years."
