People think they are dicks because they speak their mind just like the rest of us. Some people feel that even if they get a little success, they are suit and tie wearing guys who should always have something respectful or something everyone agrees with because that's the professional thing to do. However both guys are people, humans who just like us say irrational opinionated things that you can either agree with or disagree with. They've never disrespected anyone's race, body, weight or anything personal to people but only said a few things about their platform of choice. Now they are dicks because they can't act like people...
Don't listen to everyone else. They can talk about all the platforms I may hate or love but they aren't dicks Imo for speaking their minds. Some people act like they are so much better when half of them who don't like them.. Say the same stuff stupid stuff that they do on the same topics.
Saying Japanese games suck to a Japanese dev in a room full of other devs at GDC isn't being a dick?
