In a few short weeks, the PlayStation 2 will turn 20. It was released March 4, 2000 in Japan, with the rest of the world eventually getting their hands on it that fall. It was backward compatible with games for the original PlayStation, and also played DVDs. (Personally, it was the first video disc player I ever owned.) And of course, there were the games. Shadow of the Colossus, Kingdom Hearts, Katamari Damacy — plenty of classic titles and series got their start there, as well as new installments in famous franchises, like Metal Gear Solid 2 and Final Fantasy X. The system was ultimately in production for a whopping 13 years, with more than 4,000 games released in total and over 155 million consoles sold.
