Growing up in a family without much money, one of my favorite things about the disc-based systems of yesteryear (especially the Playstation) was the demo disc. It seemed like hundreds were made, covering everything from a truncated alpha or beta version of a single game, to collections of demos of games of various genres. Some had bonus features such as behind the scenes videos, too. You could get them almost anywhere- packaged with consoles, with magazines, bundled with other games. Even Pizza Hut gave away Playstation demos! Does anyone still have their demo discs? If so, what's your favorite demo or demo disc?
