Although this is the third game in the series i have to say this is the best one yet. The graphics and whole feeling to the game seems different from the previous games and makes it altogether a better game.
I bought this game as i had a few friends who had the game and when had a few beers we would play this. But it was one of those games which doesnt exactly grow old. After completing the game you can then go on to defeat the other difficulties where at times you will think "how on earth am i going to get that good".
The game has a fantastic set list, where it ranges from classics from the 70's to some of the latest songs which have recently came out. If you have the money avalible then buy this, if you havent already.
