The game Adventure, AKA Advent, by Will Crowther is sometimes considered to be the first text adventure. It was first released in 1976.
The expanded 350 point version, released by Don Woods in 1977, is also a classic. I recently ported it from Inform 6 to PunyInform, and built disk images for lots of retro computers, including the Commander X16. Get it at https://microheaven.com/advent/
This game, in different forms, has also been known as Very Big Cave Adventure or Colossal Cave Adventure.
Collect treasures, put them in the well house. Avoid the trouble makers.
