So another thing that's been bugging me is, there's no PC pixel art in there. And I wonder, does pixel art on early IBM computers not have sufficient relevance, or maybe not in the USA? Here in middle Europe, it was more the other way around, consumer gaming consoles were often enough minor. I never played even Mario, nor any other console games, ever. Some did, heard about it, but it just wasn't necessarily that big a thing for us.
I grew up on first ASCII code games on IBM computers with monochrome screens, and then on all kinds of "indie" shareware pixel games (funny this was actually a big thing in the past, too.), and then bigger commercial games like Monkey Island, Maniac Mansion, Day of the Tentacle (Point&Click adventures of Lucas Arts), or Warcraft, or Settlers, or Sim City, or Lemmings, or Commander Keen, or Command&Conquer, or... There were a great many pixel art PC games, and only they defined pixel art for me. I don't know exactly how exclusive they all were to PC, but often they were mouse/kb heavy controls. I don't know if that's a territorial thing, and if for example Settlers is nothing compared to a Mario on global scale, so that it would not be worth mentioning on such list. But in my youth, where I lived, it was the other way around. Anyway, not exactly sure which PC titles to prioritize though, maybe genre success, or what. And since PC is such a homogenous era for most people, compared to clear cut console generations, many people don't exactly tie it with pixel art anymore, they connect it more with the transit away from it, but it did start with some iconic pixel art games, even though they were work machines.
