Given
that pop music doesn’t work as well in music games as rock tunes, it’s understandable
to think a Beatles version of Rock Band would
be less challenging, and thus less fun, than, say, Guitar Hero: Metallica. But by not just mixing Rock Band with The Beatles 1,
Harmonix has made a game that’s as engaging as the Mop Top’s best work. For
starters, such early pop tunes as “Twist And Shout” now have two more vocal
parts to play, with the three-part harmonies adding as much challenge as they
do authenticity. Similarly, the tunes from their later years include some of
their rockier (“Back In The U.S.S.R.”) and more esoteric, and thus complex,
tracks (“I Am The Walrus”). Beatles: Rock
Band also takes a cue from Guitar
Hero: Metallica with its attention to fan-appreciative details. Not only do
you play such relevant venues as Shea Stadium, The Cavern Club, and the Apple
Corps rooftop, but you actually play the same songs they played there, with
each tune including previously unheard studio chatter from their respective
recording sessions. None of which makes this rock like Metallica’s game, of
course, but considering that they could’ve just slapped Abbey Road’s tracklist onto Rock
Band and cashed the check, this game turned out pretty fab.

I had some friends over to play this on Friday, and it was a blast; the track list is eminently singable. The one caveat I'd give is that the game is very short; until the DLC albums (Abbey Road, Sgt. Pepper's, Rubber Soul) come out, you're pretty much limited to 45 songs plus "All You Need Is Love."
Really, folks, for more in depth reviewing? Even I do a more thorough job.
