Guitar Hero was a very big stepping stone into the world of music games, but it left us wanting more. Thankfully, Rock Band filled the void. With two guitars, a drum set, and a microphone, the game became a cultural phenomenon that appealed to music heads, families that don't hate each other, and people in Toledo who need entertainment on Friday nights. So while GH may have opened the door, RB set the bar. And it didn't even have to resort to homoerotic ads with Kobe and A-Rod!

Players have made more than 30 million song purchases of Rock Band's 600-plus downloadable tracks.
