Well. Most people on Itch are hobby developers and struggling developers. The people that make enough money to have this as their full time job are rarely talking in this message board.
And game developer is basically an office job. Even if you work from home, because you have no office, because you are unemployed self employed.
I suggest you try reading about experiences of non indie game developers. Not about success stories of small developers gone viral. I talk about the regular people that are employed by medium to big game studios. I would guess their work is just about the same as that of any other person that works in an office on a computer.
