If you purchased the first, there was a good chance you'd grab the second, if only for that monster song list. If you gave the first a pass, now was your chance to join the music rhythm phenomenon via the folks behind pushing the genre to extreme levels. At least that's one take on things. The other is that Rock Band 2 doesn't exist in a vacuum. The game has a growing list of competitors, and while Rock Band certainly seemed to have won the first round, round two is still up for grabs".
