Like any other Guitar Hero game, this is just a fun game to play. Metallica is one of the best metal bands of all time and there is really no better band to make a game after. The songs I feel are harder later in the game, so there is definitely a challenge for all you guitar hero freaks out there.
While I did enjoy this game.. all the Metallica songs that were on here available for play, the game becomes stale really fast.. Once you play it a time or two you really lose interest in it. There were also a lot of songs that should have been on this game that were left out also.. but overall it is a good game if you want to get your Metallica fix.
personally i love metallicas songs, i am a long time fan of there music, and to be able to "play" some of there best songs was completely awesome. but there were sooooooo many metallica songs that definitely should have been on this game that weren't. songs such as "the day that never comes", and "blackened". those are two of there best songs (my opinion of course). like i said the songs that are on there are completely awesome and this a great game, probably my favorite GH game yet. but honestly, i am a little disappointed at the songs that are not on this game.
