1. Overhauled Xbox Live/Online Gaming
Xbox Live completely revolutionized how people play online video games together. While both the Playstation 2 and the original Xbox possessed the capability for online play, it was somewhat convoluted, requiring multiple extra pieces of equipment, the availability of ethernet and more. The Xbox 360’s version of Xbox Live was streamlined and an overall better experience for everyone; with the introduction of wi-fi and stronger connections to the online servers. With this improved experience, stable, online multiplayer flourished; games like Call of Duty, Halo and Gears of War had dedicated online multiplayer servers and still do to this day, as a result of the massive popularity of online multiplayer that Xbox Live introduced us to. Console online multiplayer has never been the same.
