Hunt the Wumpus is developed by Gregory Yob on a time-sharing system at the University of Massachusetts in Dartmouth. This is not an adventure game (it's a text-only maze game), but a precursor (Hans Persson, Adventureland timeline).
Atari is founded by Nolan Bushnell.
The second edition of the Chainmail miniatures war-gaming rules are published, including a "fantasy supplement." This ruleset will go on to inspire Dungeons & Dragons ( D&D ).
