It's not Crowther's Adventure, but the Infocom games.
Infocom's games were based on Crowther, after all. I remember porting
the PDP-10 FORTRAN to CDC 6000 SCOPE 3.4. I got the source from a friend
who was a DEC CE. After converting the source tape, the "save game"
was probably the biggest difference in implementation. I used FTN
(FORTRAN extended) to do the deed, rather than RUN.
After the game had been distributed at CDC SVLOPS, there was a concerted
effort by management to purge the thing from all of the permanent file
catalogs. Luckily, management never discovered who introduced the game
in the first place...
So yes, Adventure/Colossal Cave did run on an honest big mainframe.
I never played the game much myself, as I had access to the source, so I
knew the innards of the game.

Loosely based, of course.
And Bob Supnik?s FORTRAN version was also ported to VM/CMS, so that?s two mainframes.
