Calling Peter Molyneux a scammer is rather unfair. He does not set out to cheat you out of your money. He's simply a game designer that once was one of most brilliant talents in the industry, trying to capture the muse again.
It is an undisputed fact that most of his recent projects massively over promised and undelivered. It's an unfortunate truth that his claims cannot be trusted anymore.
That said, there is no malice behind it. Simply ambition that's not matched by ability to deliver.
I keep hoping Molyneux will once again succeed in one of his projects. It would be glorious, and it would shift gaming landscape, just like his old works did. At the same time, I'm no longer expecting it to happen, and certainly not getting invested emotionally or financially in any of his promises.
(Molyneux or not, don't pre-order by the way)
