Possibly one of the most straight-forward sequels, Rock Band 2 doesn't really add anything new to the core gameplay, but simply adds new features, mainly focusing on online play which added VS modes. Whether it was solo on a single instrument, or with an entire other bands, you can duke it out to get the highest score in a shared song!

Something worth mentioning that I thought was insanely based, this game let you transfer over nearly all the songs from the original Rock Band game (if you have the disc) in order to merge everything into this new game! What's that? Not cool enough of Harmonix? How about the fact that they made all mainline DLC for the lifespan of this game applicable to the original Rock Band as well?

And the rockin' cherry on top was "Rock Band Network" which allowed bands and producers to create tracks for songs they have full rights to and include them as DLC (mainly just for Xbox 360 while Wii and PS3 had limited versions of this)! Absolutely insane. I understand the milking contest was raw between Harmonix and Neversoft while they built Rock Band and Guitar Hero respectively, but I always felt Harmonix had a lot more heart and soul when it came to their products.
