D/Generation is an action-adventure game with puzzle elements developed for the 8-bit Apple II during the late 1980s, but instead published and released for MS-DOS, Amiga, and Atari ST by Mindscape in 1991. The game takes place in a slightly cyberpunk futuristic setting in 2021. It was ported to the Amiga CD32 in 1993, allowing use of the 6-button CD32 gamepad.
