Modern-Gamer writes: What can be said about the concept of music based Greatest Hits albums? In some cases they can propel an artist to a new audience. In other cases it's just another product for long time fans to blindly purchase. In the case of video games, things are a little different. For a game like Guitar Hero Smash Hits, both cases could work out for gamers along with everyone else involved in the game. In this new iteration of Guitar Hero, you get a list of great songs from the Guitar Hero series. However, is this just an on disc song pack or is it a needed edition to the franchise?
