It sounds like you're describing "frotz" which most distros have 
in their repositories.  It will allow you to play those old 
"Z-machine" games (Scott Adams, Zork, etc) as well as many new 
titles that continue to be created.  Searching the web for 
"interactive fiction" will turn up a number of (almost always 
text-only) IF games that can be played via the console on Linux.
