My theory for why PC gaming is looked at with less nostalgia than console gaming, and is thus less documented:
While consoles have nine generations, there’s really only two generations of PC gaming: DOS (appr. 1981-2001) and Windows (appr. 2001-Present). The dates are fuzzy, but that’s the general delineation.
DOS gaming is looked at with lots of nostalgia. Windows gaming, not at all. And it’s not because Windows gaming is bad, it’s because even stuff released in 2001 feels modern since you generally don’t need emulation to run those games.
