I think it’s cause of envy. Every once in a while, a game comes that just seems to do a lot of things and become very very successful (like red dead and gta).
Then these other studios get FOMO and turn to a go big or go home attitude.
So what you end up with is this inflation of features when only a few devs can land a big game like that.
I think a better word would be common skilled labour instead of unskilled labour.
The whole idea is it’s a skill that the majority can pick up, then people used it to mean it’s worthless…
