Awe, I was hoping to see a Hadean Lands mention in the book, but it was on his “these didn’t make the book but are great” list.

The list of games written about can be found on his substack archive here: https://if50.substack.com/archive

Universal Paperclips, mentioned in the book, is a journey. What starts as a clicker game turns into so much more. It’s a free browser game, but in that old-time sense of freeware.

Oh wow, I vaguely remember a misspent childhood on MUDs and MUCKs. I wonder if any of them are still going…

It’s worth mentioning the Interactive Fiction Archive, a massive catalogue of hobbyist-created text games, many based on free text game engines like TADS.

Ahh, good times. One of my earliest uses of the web circa 1996 was Invisiclues for Zork II. I didn’t have access at home, so I had to play until I got stuck, then look up the answer at school the next day.
