Here is an article from 1982 arguing that more video games should have a coop mode: https://archive.org/details/Softline_Magazine_Issue_1.5/page/n49/mode/2up https://archive.org/details/Softline_Magazine_Issue_1.5/page... Also there was a bit of a solo boardgame boom around 1980 with some games also supporting (or at least suggesting) playing together with others, but it was somehow forgotten and then someone rediscovered around 2010 or so. I find it strange that I never saw a coop game from before the late 1970's though, and it is not because I have not been searching for them.
