Turns the quote of "A late game is a game that arrives late, a rushed game remains bad forever." is not from Miyamoto. It's from a trans game dev from 1982/1992 named Siobhan Beeman.

While tweeting about my latest attempts, a mutual pointed out to me that the reason I’ve been having trouble finding her is that she’s since transitioned and changed her name to Siobhan Beeman. This is such a not-uncommon occurrence in the gaming industry that, honestly, anytime I can’t find someone and there’s no obituary, I assume they’ve simply transitioned.

Thanks to this new lead, I was able to get in contact with Beeman and ask about that GDC panel, and she confirmed: “To the best of my recollection I came up with that phrasing. The sentiment certainly existed in the industry, especially at places like Origin.” Beeman was the project director at Origin from 1989 to 1992.
