Soldier of Fortune 2 had a procedural level generator in it. It would take a random seed, a mission type, and a terrain; then generate a one-shot mission for you to complete.
I thought it was brilliant, and it kept me entertained for hours and hours.
This is a similar concept, just taking AI / ML libraries and letting them run wild, instead.
Did Soldier of Fortune 2 allow users to share those level seed, too?
You could write it down and send it to a friend like progress codes in old-timey games. :D
