Get the guitar!!! Completely different game and much more realistic. I am not a video game person but have the Wii and bought Guitar Hero for the kids
but my wife and I play it all the time as well.
We have two guitars so us and the kids can battle each other.
So far I have made it thorugh all the songs on medium except for "Through the Fire and the Flames" although I can do this song on easy and hyperspeed #5
Now I need to pick up Rock Band which just came out this past Sunday
Rock on dude
