The chillest shape of all. Chiliagon has 1,000 sides and can be mistaken for a circle. It's one of the biggest shapes that actually has a name, and that's logical. I also probably wouldn't want to name a shape with 6,454,740 sides.
6 year old Timmy: look mom, i drew a chiliagon!
Timmy's mom: what the hell is a chiliagon
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.
