Android Nim
Android Nim was a game written by Leo Christopherson for the TRS-80 computer in 1978. A version for the commodore PET by Don Dennis from Toronto Canada was released in July 1979. A new version rewritten for the PC was released in 2005.
The object of the game was to remove the last android from three rows of androids. The game's premise was simple, but its animation was impressive given the limitations of the TRS-80's 128 x 48 pixel display. Throughout the game, the androids were animated to face in different directions, almost as if out of boredom or as if they were engaging in conversation with one another.
The game starts with three rows of androids which contain: 7, 5, and 3 droids respectively. An animated android asks the player if they would like to go first. The player chooses a row: A, B, or C -- and types in how many droids to remove. An animated droid at the head of the row then nods its head and raises a gun. The other androids turn to look at the selected row. The specified number of androids are then zapped with a laser beam. It is then the computer's turn - with similar effect - and play continues until the last android is removed.
If the human won, the computer was an amusingly poor sport, and displayed adjectives of astonishment, and if it won, declared it with a huge "I WIN!". If the computer was about to lose, it would pretend to seek futile ways to avoid losing (i.e. by selecting more androids than were available on a given row) before giving up.
