Sorry to continu the be off topic, speaking of guitar hero and rockband, I want to sue guitar hero for being such a bad game. I got an injury in my left hand that forced me to stop playing guitar for 6 months! It was during one of the hardest song from slayer and the Guitar Hero guitar pattern was just not doable. I tried to play those buttons combination and got a pretty bad muscles burnt (don't know how to say it)
On the other hand, I like rock band, they have better patterns that lead to a more real feeling. But since my injury I only play the fake drum, it is fun! (injury long gone now, I can play may real guitar and got most of my technique back) I'll never touch that plastic guitar again, it is just awefull.
The drums is an awefull lot of fun to play, give your kids a go, I'm sure they will envy to play real drums afterwards!
The beatles game seems promising! On a musicological level, Ringo's drums is not the funniest, but well it may be after all!
