This is one of the main reasons I was happy to leave the game industry after eight years of doing it.
Working incredibly hard to build a product served to a group of people that are often hurtful emotionally stunted man-children is just a deeply demoralizing experience.
Obviously, many gamers aren't like that. But a fucking whole lot of them are, and they are extremely vocal, and it doesn't take many of them to suck the joy out of the job.
Imagine a bar where every time you walked in the door a half dozen dudes invariably turned around on their barstools and told you your clothes look like shit, your face is disgusting, you hair style is stupid, you smell like trash and, you should just fucking kill yourself now. How often would you want to go there?
Unfortunately, I think games themselves often encourage this mentality. Most games are about making the player feel empowered inside a virtual universe that exists purely for their own exploitation and satisfaction. The whole point of playing games is to get an escape from the consequences of our actions.
People that are strongly drawn to that or spend too much time in that mindset are basically training themselves for a toxic mindset when it comes to interacting with actual humans.
I think a lot about this talk by Max Kreminski: https://www.youtube.com/watch?v=TvlZinAvpwg
In there, if I remember right, he refers to many games as "entitlement simulators", which is a profound truth.
