+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 influence, but not dnd; like PLATO itself, dnd seems
+not to have become known outside of its own user community 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 (much) later included as a monster in the
+Nethack roguelike game, this was done in a spirit of conscious
+museumization well after early roguelikes. There is no evidence that
+Yob's original (circulated in BASIC among microcomputer enthusiasts)
+was known to the ARPANET- and minicomputer-centered culture Crowther
+and Woods were part of until well after Adventure was written.
+
+Neither of these games used an attempt at a natural-language parser
+even as primitive as Adventure's.
