Now I want to assess the instruments in individual times.
Drums:
As a very negative I would assess that the game is not 100% compatible with the GH Warriors of Rock Bundle Drum or the Logitech drum. Although you can with the aforementioned drums play the game but it will not be counted all marks, characterized one often loses the multiplier and is not coming to the point even though I still have 95-99% in medium and heavy on average. There are also here to play only 4 Beck keys + the foot switch, for GH Drummer it means a short familiarization phase.
Guitar:
In this game work in both the GH Metallica guitar, and the guitar of GH Warriors of Rock Bundle.
Playing this instrument is different to the GH's hardly and fun whether guitar or bass.
Microphone:
The microphone of the GH Warriors of Rock Bundle works very well in this game.
Conclusion:
A successful alternation Empire music game that is fun both alone and as a band on- or offline.
Since I personally prefer but drumme and when the game does not work properly as it should I give the game by only 3 stars.
