Easily the best Rock Band game so far.
I find their music very boring and somewhat depressing so it was pretty tough for me to even pick this game up.
Basics: The Beatles RockBand game is by far the best Rock Band game so far simply because they fully captured what The Beatles were all about. The background scenery and visuals really take you back to when The Beatles reigned supreme in rock and roll.
Gameplay: Not much different from any other Guitar Hero or Rock Band game. The only real significant difference i saw in this game compared to others is that the difficulty is improved.
Example: Any -REAL- musician who has ever played a Beatles song knows first hand that their music is very simple and repetitive. What i was really happy about in Rock Band: The Beatles is that they didnt make expert difficulty harder than what the actual songs are. Very realistic and VERY FUN to play.
I recommend this game to anyone who enjoys a killer party game or even someone who isnt sure of which GH/RB game to pick first. Even if you dont like The Beatles, i definitely recommend that you pick this game up, even if you rent it first. Those who have played this game will realize that its far superior to its predecessors.
