The Scott Adams adventure game series was published around 1978-83, and started on the TRS-80 Model I. I don't know if there were ever official CP/M ports, but they were certainly of that era.
Thanks for the clarification! I hacked TRS-80 Model I hardware (for a friend), but I never cared much for TRSDOS or Lifeboat so I have missed out on that software experience.
I guess this was a port of the classic Adventure game to Tandy. I had the CP/M version (550 point Colossal Cave Adventure). I had played it even earlier on RT-11 where it took about half an hour to load from two 8" floppies.
