The impression I get from TFA is that this is about "unfinished/unreleased" games more than "lost" games. A "lost" game, film, or work of literature would be one that was published or released, only to disappear again from the historical record. https://en.wikipedia.org/wiki/Lost_literary_work https://en.wikipedia.org/wiki/Lost_literary_work https://en.wikipedia.org/wiki/Lost_media https://en.wikipedia.org/wiki/Lost_media Several lost games from the text-adventure world are listed here: https://www.club.cc.cmu.edu/~ajo/in-search-of-LONG0751/2009-02-02-lost-versions-of-adventure.txt https://www.club.cc.cmu.edu/~ajo/in-search-of-LONG0751/2009-... https://ascii.textfiles.com/archives/2923 https://ascii.textfiles.com/archives/2923 (BlackDragon and Dor Sageth) https://web.archive.org/web/20140528184628/http://games.wwco.com/pits/ https://web.archive.org/web/20140528184628/http://games.wwco...

(To be fair, many of the games listed in the latter two posts seem to be known only via advertisements; it's conceivable that those advertised games might never have existed. But in many cases we know a game existed because we have testimony from people who played it at the time.)
