The PlayStation Two, or PS2, is Sony's successor to the original PlayStation (PS1). It features an improved CPU, better graphics, online gaming capabilities for certain games, two USB ports, two Memory Card ports and two DualShock ports. It hit the market in the early 2000s, and is considered one of the most popular and greatest video gaming consoles of all time. It is the best selling video game console of all time.
The PS2 has been superseded by the PlayStation 3, which (alongside the Xbox 360 and Nintendo Wii) is a current-generation gaming console, and is the platform for Grand Theft Auto IV and its episodes, The Lost and Damned and The Ballad of Gay Tony.
