+There is record of one earlier dungeon-crawling game called "dnd",
+written in 1974-75 on the PLATO system at University of Illinois
+<<DND>>.  This was in some ways similar to later roguelike games but
+not to Adventure.  The designers of later roguelikes frequently site
+Adventure as an explanation, but not dnd; like PLATO itself, dnd seems
+not to have become known outside of its home university until
+rediscovered by computer historians many years after Adventure
+shipped.
+
+There was also Hunt The Wumpus <<WUMPUS>>, written by Gregory Yob in
+1972. Though the wumpus was later included as a monster in the Nethack
+roguelike game, there is no evidence that Yob's original (circulated
+in BASIC among microcomputer enthusiasts) was known to the ARPANET- and
