Back when I was into pins, most everything I read was from RGP.
I don't know if it was just an odd attitude for the fellers on that site or if they were correct, but back then I got the idea that Wayne G. never did much for pinball ever. After the Medieval Madness madness, once I heard the CH hunter project was scrapped I wasn't surprised at all. I just remember thinking that if half the talk was true and Wayne was as capable of creating a new game from scratch as he was on the MM remake or other (lack of) contributions to pinball, then even if the Irwin family hadn't experienced their tragedy the pinball game would never have reached completion, let alone production.
Again, I don't know how accurate the portrayal of Wayne was and all my info came from RGP. But I am certain that I would have required much proof before sending any money Wayne's direction. There seemed to be a lot of "bad blood" back then.
