Not wanting to derail the topic from @forager23 here, so making a new topic.
Where is the “latest” link for The Shadow of Yesterday? The wikipedia page seems a big vague.

This is a currently working link to an HTML version of the 1st edition rules text (though I’m not sure how complete it is):

It’s at least a reasonable starting place to get a feel for some of the important ideas.
The official website has links to on Lulu Clinton Dreisbach - Games
It’s a great game and I have a copy. Let me know if you have any questions.
