Honestly I'm really surprised its taken this long for someone to really take this kind of approach with Peter and after all hes said over the years no I really don't think starting out by asking him if hes a compulsive liar is out of line.
It's not like this the first time Peter has over promised and under delivered, hell its likely not even the 10th time. The guy admits he lies about his games to keep press interested, there is no reason anyone should defend him in any situation ever.
I'd go as far to say I think at worst hes a con man, a man who might have some brilliant ideas but he has NEVER actually made any of the those ideas a reality and he has conned gamers and publishers time and time again making it seem like he can do these amazing things which have never been done before and frankly he is not that good of a designer to ever be able to make any of his ideas a reality. Even in this very interview you can catch him lie in several different questions that are asked one after another. It's crazy that the press HASN'T called him out for this before. Hes lied to everyone in this industry even his own teams and yet the guy actually still got as much money as he did from his kickstarter and now clearly will never actually give the proper rewards out to the backers.

And with that said, I wish we had more people in games journalism who would take the stance this article does with Peter for other developers and publishers. When Mass Effect is eventually going to be shown off this year or next does anyone think the press is going to actually take Bioware to task about how they directly lied about how the ending of ME3 would play out? What about EA in general with everything they did with Dungeon Keeper publishing them saying it was 'to innovative' rather then calling them out on the scam that the game was. What about BF4 and how the reviews were set up to give an optimal experience at the review events only for the game to be broken 6 months after it launched.
Hell look at EVERYTHING that came out late last year, Unity, Halo MCC, Destiny, Dragon Age, ect. I like several of those games but they came out with god knows how many problems or just were not actually what they were originally advertised to be (Destiny in particular in this area) and the only reporting we got about this was largely just 'yeah this happened and what can you do' instead of actually lighting a fire under Activision and Bungie for the outright LIES they promoted the game as having.
We need more journalists like this and less ones that just say whatever the PR of whatever publisher wants them to say.
