Just a question: how many of you have actually watched that gametrailers episode? (The part is near the beginning, so there's no need to watch the whole stuff).
I really scratched my head on it. My guess is that they've sent out Marcus with questions that neither Blow nor Fish were allowed to answer, which left Marcus with pretty much nothing to talk about. So he just goes below the belt and attacking them (and mostly Fish) personally. If you want to call someone immature, you can start right there. And it could just be me, but I think that talk show host (on the left on the screen) kinda wanted to redirect the trashtalking back into talking about talking about a game, but wasn't quite sure how to do it.
And another question: there are plenty of indie developers out there (he mentions the makers of torchlight, no less!). Instead of complaining that Blow and Fish get all the attention from the press (which is actually kind of complaining that he himself is giving him that attention), couldn't he just contact someone else, rather than expecting answers to questions they were probably not legally allowed to answer in the first place?
Quitting game development over this is probably kind of harsh, but I wouldn't call that definite either. The press plays a large part in the reception (and thus sales) of a game, and with this sort of incident it'll be hard to recover from. It's no incident that large companies spend many millions on publicity (in other words: more than the total budget of the average indie game). It's not exactly fair to expect the same sort of professionalism from small (or even one-man) companies, right?
