And then I suppose the restaurant industry will crash because the meals they picture on the menu look significantly more delicious than the meals you actually receive?
And the do-it-yourself furniture business for showing pictures of furniture that actually work when the thing in the box ISN'T EVEN CUT RIGHT HOW AM I SUPPOSED TO PUT THIS DESK TOGETHER WHEN THE DRILL-HOLES AREN'T LINED UP WTF
Completely different to the example at hand. Both those things are necessary and don't REALLY have an equivalent that can be used instead. The video games sector is based on entertainment, (therefore competing with EVERY OTHER entertainment form) it's possible to pirate most games and there's a lot of games for free if you don't want to do that.
Basically, it's an entirely unstable market based on customer satisfaction and expectation. If you continually hype up your games to be the best things since my brass balls and then fail to deliver, then you're going to have no one buying your games no matter how much hype you throw out there.
With restaurants, I'm not a professional chef and they'll probably make better tasting food than I could, as well as waiting on me hand and foot and in a nice setting. With DIY furniture, it's necessary to survive, for all intents and purposes. They only compete within their own markets.
