Ok, so admittedly I am a HUGE Van Halen fan. I love both David Lee Roth, and Sammy Hagar. Although I'd love to see/hear some Van Hagar songs on this game, the DLR era songs on here are awesome classics, and very fun to play.
I loved the trivia facts that you can read while the song plays once you've bested the song.
The non VH music on this album is a pretty good selection of music that I like personally. Much much improved over the insanely odd/eclectic collection of music on GH5. Coming from someone that is very eclectic in their music tastes that's saying something. :P
GH VH doesn't make any huge improvements or changes to the formula. If you are tired of rhythm games, then you'll be bored with this one, but if you are a fan of the band and their music, you will probably have fun with this one.
Speaking of missing band members, this just isn't the real Van Halen without at least a tribute to Michael Anthony, but sadly the great Eddie VH threw a pity party and basically has tried to erase his existence from the band completely. But really this is just a trivial fanboy complaint.... the game rocks for me. Personally, I think this is the best kind of band for a true Guitar Hero game. Van Halen is a true Guitarist's band, with Eddie VH being one of the best guitarists of all time.
