We'd be here all day if we listed 80s computer game so I'll just to confine it to strictly 80s (and early 90s) graphic adventure/text games since those are more directly related to the CYOA style on this site.
If you're bringing up Zork, you might as well take a look at the whole Infocom line of text games during the 80s. Pretty sure there is a website where you can play them for free and I know there is a "Infocom Lost Treasures" app.
I particularly liked:
The Hitchhiker's Guide to the Galaxy
Leather Goddesses of Phobos
The Lurking Horror
If you want graphic adventures, Activision, Sierra and LucasArts are the major companies that come to mind.
Activision came out with a few interesting ones with some odd settings. The two that I remember were Mindshadow which didn't seem weird at first but later had some really anachronistic stuff going on it (At one point you're on an old style pirate ship, the next you're in a modern style city) and Tass Times in Tone Town which is REALLY a product of its time set mainly in an alternate dimension where everything has a New Wave/Punk style and guitar picks were currency.
For Lucas Arts, Maniac Mansion was the most popular at the time, though Zac McKraken and the Alien Mindbenders was okay. I'm sure you've heard of the Secret of Monkey Island series, but I really thought their Loom game was a setting that had a lot of untapped potential.
The very first one they did though which doesn't really get remembered nowadays was Labyrinth which was very loosely based on the movie. It was sort of unique in that it started out as a regular pure text game, but when you eventually got transported to the Labyrinth it turned into a point and click style, though it had a "text wheel" which was a predecessor of what they would use later in their other games.
For Sierra they had King's, Police, Space, Hero "Quest" series, but I never got into those. The only two major series of theirs that I ever got into was Leisure Suit Larry and the underrated Manhunter series. Some of their single graphic adventure games were cool too. (Rise of the Dragon, Conquests of Camelot, etc.) A lot of Sierra's graphic adventure games seemed to incorporate some action sequences or mini games in them.
And of course there were many others. Uninvited was a good one as far as horror ones go. Farmer's Daughter was a short and much lesser known text game, but it was pretty different from anything else I had played at the time so it stood out to me.
