1. I mean, I think being a bit opinionated is good. But its a scale, right? Its not a YES or NO. Sticking to your guns is good, you shouldn't drop all your beliefs the second someone says otherwise, but you should be open enough to learn new things and change your mind if strong enough evidence, or personal experience, comes your way.
2. Existential Crisis is the lifeblood of sports car dealerships. So, yea, I imagine everyone does.
3. I mean, it was just Atari. I really can't imagine the 'world of video games' would be that different if Atari hadn't pulled a Hindenburn. You'd still have PC being the big one [Since the introduction of the PC really smacked down the Atari], mobile gaming being a thing and the rest of the market share being taken up by the few consoles strong enough to survive... And I still don't see Atari surviving unless they go full Nintendo [IE, grab a few successful IPs in your iron grip and grip them so hard you can survive even when you are incredibly anti-consumer and just... way behind everyone else in every field] especially since Atari weren't exactly the most business savvy, seriously going to need some changes for them to survive. A big part of the video game crash was Atari's fault [massively overvaluing themselves and their product along with mass production of horrible games that killed consumer trust, loss of IP control and an oversaturated console world that was destined to weed out those that couldn't survive], so... Nah, its whatever. Free Market, strong survives, play stupid games, win stupid prizes, pick whatever phrase ya want.
