Can you describe where in the main menu this text lived? I can’t find a screenshot and want to jog my memory.

Commander Keen, Space Quest, Duke Nuke encapsulate my earliest memories of using a computer.

In the main menu of Commander Keen 1: Invasion of the Vorticons, there's an option called "Previews!" (between "Ordering Info" and "Restart Demo"). First it shows a couple screenshots of the next two games. Then a text screen with more details appears. It can be scrolled up and down. At the very end there's a description of what would eventually end up as Quake. It was quite different from what we actually got. Only the "Quake" name survived, I think :)

		Amazing - I just remembered that all these old games are playable via the internet archive. Fired it up, followed your instructions, and found the text. I don’t think I ever explored that menu option as a youngster. Seeing that blue wolf-like man before the text appeared sent a chill down my spine. Thanks for enabling this blast from the past.
