Well... As much as I love the Beatles, I was a little disappointed in this game. Before you flame me, hear me out.
Their music is absolutely amazing. However, I find that I prefer Guitar Hero over any Rock Band. If I were to compare Guitar Hero 5 with The Beatles Rock Band, I would say Guitar Hero wins.
The Beatles Rock Band is just... The music is great, the graphics aren't that good, the screen while you play overall isn't as great and detailed as Guitar Hero, and the backgrounds aren't my favourite.
In more detail:
The Music: is great. Strong, clear, and awesome. It is The Beatles after all.
The Graphics: hmm... While you're playing, and the background shows the musicians and the audience, the graphics are pretty well done. However, the loading screens and the main menus aren't that great for me. The colours are just... Messed up for my taste.
Overall: I would give it an 8.5 out of 10. Itdoesn't give me the samevibe as Guitar Hero.I have to say though, the opening scene is just awesome.
If you're a die-hard Beatles fan,go for it. You'll fall in love with them all over again :)
