Mine was Apocalypse / ApX (a hack of Havok, which was a hack of something else, which was a hack of Emulex/2, which I think was a hack of Forum?), around '92.
I, too, remember recruiting ACiD guys to help out with the menu art.
Ah, memories.
You'd actually have to add delays by moving the cursor to allow enough time to read the captions/speech bubbles. It was pretty funny because it would be much slower on a 300 baud modem vs. a 2400 baud, so you had to be careful how you tuned your delays.
All written in turbo pascal, right ?
Pretty much everything was either a Forum (Pascal) or WWIV (C) hack.
I also remember some very, very active and high quality boards that ran citadel ... citadel was sort of the HN of the BBS world ... no ANSI, no fluff, just quick command keys and all high quality discussion.
This meant it could offer an active chat room, and it had a MUD game that everyone loved, called TeleArena.
For me, TeleArena was fun because I'd write scripts that would automate playing the game for me when I wasn't there.
I had this weird software I licensed which let people play Doom against each other, over the phone line, simulating a local IPX network ... MPGS (Multiplayer game server) by a company called APCi.
