n. software that is no longer sold or supported by the original publisher / developer, often found as free downloads on the
internet because it cannot be obtained elsewhere. Not
legal, but often seen as morally acceptable because the company that made it is no longer selling the title, nor releasing it as freeware, therefore abandonware is "keeping the
game alive", so to speak.
Doom II is not abandonware because
id still sells it, while The Incredible
Machine is not sold, therefore is abandonware.
