In four different difficulty levels, there are respectively 25 songs that can be rehearsed before concerts in unevaluated practice mode. That you always have to play the same song, which is a star which I have withdrawn. In career mode, you can create for the three players who can earn his own money and unlock different things, for example, characters, guitars or clothes.
I do not know the other Guitar Hero games, but I heard that they should be very good. So I do not know if this game meets the requirements of GH fans, but is well worth a recommendation.
As I said, the pain was with me only the beginning, but that seems individually to each player on.
