Interesting news for historians of digital culture. I had no direct knowledge of this game. I want to learn more about it.
Wander was probably the first computer game that is recognisable as what came to be known as a “text adventure” (or “interactive fiction“) – pre-dating even ADVENT (a.k.a. Colossal Cave) by Crowther and Woods!
But Wander was more than that because it seems to have been designed to be a tool to allow users to create “non-deterministic fantasy stories” of their own. So perhaps it would be more accurate to say that Wander was in fact the earliest known precursor to modern interactive-fiction development-systems like Inform 7! —Retroactive Fiction.
