This has a side effect of the people who went through the full game development cycle and can help to improve the process of developing of future games with actions based on their experience do not stay in the industry and thus the industry is bound to repeat the same mistakes again and again. I mean, I started working in the gaming 22 years ago, worked there for 7 years, then took 12 years of break elsewhere and now I am back for 3 years. After I returned I was surprised how almost nothing changed. It is still the demo-to-demo sprinting without proper planning or building the technical layers in advance. So the publishers/management is getting more or less faked demos and are always surprised that at some point they get a very badly made piece of software full of bugs and architectural flaws.
