The Playstation 3, released in 2006, was a powerful gaming console that introduced a range of new features to the Playstation lineup. It featured a Blu-ray disc drive, which allowed for high-definition movie playback and larger game data storage. The PS3 also introduced the Playstation Network, which enabled online gaming, movie and music downloads, and social networking features. Interestingly, the PS3's unique Cell processor architecture made it a challenging console to develop games for, leading to delays and higher development costs for some titles. The PS3's library of games included popular titles like The Last of Us, Uncharted, and Metal Gear Solid 4.
