That tweet could very well be nothing but the result of anger of having giant bomb shit talk his game, but he's not wrong either way. More often than not they just seem to have this smug assholeish attitude about them. There's criticism, and than there's just being a fucking asshole deeped in cynicism. I felt pretty uncomfortable hearing them talk about Jaffe in that episode, so I can't blame him for having the reaction he did. The people saying he's salty... like come the fuck on. Get some perspective, they were straight up insulting the dude and that's not cool.
Critics in general just seem like awful cynical people, who lack the talent to create anything, so instead just shit on other people's work. Not all critics of course, and some genuinely take it seriously and try to be fair. But giant bomb has progressively turned into nothing more than a neo gaf drive by shit post as of late, that people really only go to because admittedly it's sometimes funny.
