Yes; as much as I love Game Maker, Overmars rubs me the wrong way. He sometimes mentions games on his blog, but when he does, he does it from a standpoint of "grading" them, judging each part and telling people what to improve. It feels a bit like he sees himself as a superior game designer to the community just because he made the engine, when his thoughts on the games he reviews and suggestions are often arbitrary, and sometimes even bad advice. He's never even made a game himself for the Game Maker, besides a few examples, whereas James created the Ohrrpgce so that he could make the games he wants to make.
(Of course, his day job is a college professor, and acting like he knows everything comes natural to such people in my experience, with some exceptions.)
The attitude he provides could be considered negative, but I've always seen Mark Overmars as stuck in a bit of a hard place when it comes to assessing his fan base. Just about every Game Maker forum out there is thoroughly inundated with brand new developers. Understandable, given the tool's accessible nature, and it's also pretty cool to see so many people trying the craft for the first time.
The problem is that Overmars is in a prime position to become jaded about people's work: I think it's quite possible that he's learned to deal with a lot of people's work like they were his students, or children. Or stuff. And because he gets locked in that mode of thinking, it's difficult for him to readjust said conditioning and treat more experienced devs as different cases.
I'd reckon that it's far easier to blanket brush everyone as a starry-eyed newbie than it is to assess individual skills, after all.
