PGNx Review: Rock Band 2

Start a band. Rock the world. (Again.)
The original Rock Band undoubtedly revolutionized music games in a number of ways. The first (and most obvious) is that it added drums and vocals to the standard guitar gameplay and thus allowed gamers to partake in a full band experience. The second is that it made great use of downloadable content to drastically expand the game's (already large) soundtrack. Rock Band 2 doesn't introduce anything revolutionary to the series – but it does address some of the criticisms of the first game while introducing another 80 or so songs to the series.
