Microsoft Adventure

Microsoft Adventure is a 1979 interactive fiction game from Microsoft, based on the PDP-10 mainframe game "Colossal Cave Adventure", and released for the TRS-80, Apple II, and later for the IBM PC. It was programmed for the company by Gordon Letwin of Softwin Associates.
Gameplay.
"Microsoft Adventure" is a text game of cave exploration and treasure gathering where the player enters one- or two-word commands to direct the computer to move and manipulate objects, and points are awarded for areas explored and for treasure acquired. It contains 130 rooms, 15 treasures, 40 useful objects and 12 problems to be solved. The progress of two games can be saved on a diskette.
Release.
Microsoft originally released "Microsoft Adventure" in 1979 for the TRS-80 and the Apple II under its new division, Microsoft Consumer Products. IBM later included "Microsoft Adventure" as the only game in the initial software releases for the IBM Personal Computer, making it one of the first two games available for the new computer along with "DONKEY.BAS" (which was included in the operating system). It was released on a single-sided 5 inch disk, required 32K RAM, as a self-booting disk; it could not be opened from DOS.
Reception.
Carrington Dixon reviewed "Microsoft Adventure" in "The Space Gamer" No. 49. Dixon commented that "No game that exists on several different computers can fully demonstrate the potential of any one computer. Even so, your [money] buys many hours of cave exploring and treasure snatching. There is only one 'set-up' but that one is rich and complex enough to keep anyone busy for many games. I suspect that many people will come back to the one after some flashier games have been permanently set aside." "PC Magazine" also reviewed the game positively, writing, "This hoary old classic should be included in any player's collection of games for the IBM PC."
