the game rockband comes with a mic and instruments and a disc that you put in the video game console, which has songs on it.
but, you can buy additional discs (right now the country and beatles are the only ones I've seen). but the original game does already have songs.
I think this would be GREAT for you kids since they love music! You can buy an additional guitar (one will be played as bass), and that would have you up to one singer, one drummer, and two guitarists. = ) These get up and spend time together
type of video games are the only ones I play, and I LOVE them. my sis and I have competitions on who can get the highest score = )
oh, and there are like 5 different skill levels, and you can pick a different one for each instrument, so you can even out the playing field if some of the younger kids have some trouble (my nephew is 10 and plays well, but he just has a little
bit of trouble with the lowest button on guitar since his hand is smaller)
