The PlayStation revolutionized the face of gaming by introducing 3D games that didn't require a pricey microchip, add-on, or an expensive 'multimedia system'. Then it was succeeded by the PlayStation 2, which became the most successful console ever made...eventually. People weren't actually hot on its limited library at release, including some Dreamcast ports that were mostly better on Sega's machine. Then, because it was the first out of the door, its specs and hardware weren't quite as advanced as that of Microsoft's new Xbox and the Nintendo Gamecube.
