Adventure is the fons et origo of all later dungeon-crawling computer
-games, the grandaddy of interactive fiction, and one of the hallowed
+games, the granddaddy of interactive fiction, and one of the hallowed
artifacts of hacker folklore.
+== Origin and history ==
+
The very first version was released by Crowther in 1976, in FORTRAN on
the PDP-10 at Bolt, Beranek, and Newman. (Crowther was at the time
writing what we could now call firmware for the earliest ARPANET
some in other languages - so the maximum point score is not
completely disambiguating.
-Same articles at <<DA>> are a narrative of the history of the
-game. There is an in-depth study of its origins at <<SN>>.
-Many versions are collected at The Interactive Fiction Archive
-<<IFA>>; note however that its dates for the earliest releases
-don't match other comments in the code or the careful reconstruction
-in <<SN>>.

-Future versions of this document may attempt to untangle some of the
-non-mainline history. For now, it will suffice to explain the chain of
-provenance that led from the original Adventure to the version
-distributed with this document.
+An attempt to untangle and document a lot of the non-mainline history

+original Adventure to the Open Adventure distributed with this
+document.
The original 350-point ADVENT on the PDP-10 had been one of my
formative experiences as a fledgling hacker in 1976-77. Forty years
> also details like just what _can_ you do in the dark...?

+Great care has been taken to preserve 2.5's exact gameplay as intended
+by Don. However, under the hood Open Adventure is rather different from
+2.5. Where 2.5 was written in FORTRAN mechanically translated into extremely
+ugly C, Open Adventure has been translated into much more modern and
+idiomatic C. The extremely cryptic and opaque format of the original
+database of rooms, objects, and strings has been moved to YAML;
+this makes the brilliant design of it much easier to comprehend.

== Earlier non-influences ==
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
+not to Adventure. The designers of later roguelikes frequently cite
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
until well after Adventure was written.
(I was a developer of the Nethack roguelike early in that game's
-history; we knew of Hunt The Wumpus then from its early Unix port, but
-it didn't influence us either, nor in any apparent way the designers
-of other early roguelikes. After my time the wumpus was included as a
-monster in Nethack, but this was done in a spirit of conscious
-museumization after historians rediscovered Yob's game.)

Neither of these games used an attempt at a natural-language parser
even as primitive as Adventure's.
