Totally worth it. Honestly you could have split up the song making and concert playing into 2 separate games and they both would be awesome on their own. Now songs made my two different people sound completely different from one another. The amount of options in song making is simply amazing, not to mention the controls for song making is very well done. The QWEASD controls for playing songs takes a little bit of getting used to, but a welcome addition. This game can keep someone entertained for another 6 years. Kudos man, this game is a work of art.
