According to the interviews I've read, Jon Nolan claims Wagner was the real Fallout fan of the big 3 creatives. In another interview, Wagner says that he had to turn off the part of his brain that said "you can't do that" so he could let Nolan and Robertson-Dworet run wild with turning southern California into a stupid goofy theme park. If Wagner had insisted on taking things more seriously the show could have been completely different. He knew they were wiping out everything that had to do with the west coast games and went along with it for the paycheck. He certainly doesn't have as much industry pull as either Nolan or R-D.
