Summary: One complaint: 1) there are only 18 songs. Other, more recent Guitar Hero/Rock Band games that honor one specific band (Metallica, The Beatles, Green Day) offer many more songs, making them more worthwhile purchases. If the price was commensurate with the number of songs, I'd have little to complain about (compared to Guitar Hero, the timing requires more precision and can be difficult for certain songs). All of AC/DC's best songs are here, and it is fun to play along.
Conclusion: Much like AC/DC's Fly On The Wall album, Rock Band AC/DC Live simply doesn't have enough content to satisfy. As an expansion pack, the game offers some good AC/DC songs (although this is far from a greatest hits collection). As a stand alone title, the game simply leaves too much to be desired to warrant a stand alone purchase (unless you have the original Rock Band).
Pros: AC/DC Live finally gives AC/DC fans the chance to rock out with some of their favorite AC/DC Songs. The game features such classics as Shook Me All Night Long, Highway To Hell, Back In Black, and other great songs. Also during some songs, before hitting the last note, the game will prompt players to wail on the guitar to get a higher bonus just before the last note, which can lead to some fun moments.
Cons: Much like tossing a polar bear a chicken nugget, AC/DC Live simply doesn't have enough content for those looking for a full gaming experience. The game only boasts of 18 songs total (no unlockable songs either) which are all performed live (creating an inferior sound quality). The career mode only consists of playing each song while trying to get a higher score.
Summary: Can't trash the songs here, but if you're buying this used on ebay, do NOT expect the authorization code to work so that you can play on rockband1 or 2. Its a one time code, so its not going to work unless the previous owner decided not to use it (and why would anyone not use it?) You will only be able to play these tracks off the disc and by themself. Want the full version?...gotta go shell out 40 bucks at walmart.
Summary: The only thing this standalone game is worth buying for is the fact that it has a redeemable code (making the songs available as DLC on your Rock Band 1/2 games). The game itself is terrible, looks like they took many steps back; honestly, it looks like a brainstorm project mid-development for RB2, before they even finished.
