Ingvarsson is a last name. Every ingvarsson is strict and polite. They don't share much information and keep everything for themselves. They dress grey and are a bit boring overall.
Person 1: why is he dressed so grey?
Person 2: eh he must be an Ingvarsson
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 gamealive", so to speak.
Doom II is not abandonware because idstill sells it, while The Incredible Machine is not sold, therefore is abandonware.
