How has online gaming evovlved

To be honest the first online game i ever played was Halo 2 and that is pretty much like Halo 3. Halo 3 is a top of the line online games so that means that online gaming hasn't changed too much in my eyes. The support around it is the main thing that has changed because now you have marketplaces, friends lists, movie downloads and even game downloads coming with things like Xbox Live.
