God of War's Cory Barlog says PlayStation studios convinced Sony to put games on PC

In an interview with Game Informer about the launch of God of War’s very good PC port, creative director Cory Barlog suggested that the recent wave of PlayStation games coming to PC started with enthusiasm from Sony’s studios. 

“I think it was the collective of studios all over saying this is a really good idea. We should be looking into this,” Barlog said. “Eventually, I think it reached that tipping point. When we had sent so many suggestion box suggestions that they were like, ‘I’m tired of hearing all this. Fine, we’ll do this.'”
