I ran the game and when I `suspend`ed it, it said:
I can suspend your adventure for you so you can resume later, but
you will have to wait at least 45 minutes before continuing.
This adventure was suspended a mere 1 minute ago.
Even wizards have to wait longer than that!
It's especially weird since the README encourages suspending the game every half hour or so.
So time sharing systems don’t get filled up with people playing games.
By the way, “Colossal Cave Adventure” was a retcon added at least 20 years later.
The game was originally called “advent”.

Just like the precursor to Zork was called “dungeo”[0], both due to a six character file name limit!
I still want to try emulating[1] ITS someday, just to experience the original versions of emacs, zork/dungeon, macsyma, SHRDLU, ...
Though I imagine like an online community or game it can't really be recreated since it depended on its users at MIT and elsewhere, and its specific time and place in history.
