Can any beginner or advanced-trained recommend this game. :) The game system was super implemented and the difficulty has been used perfectly by adjusting the play. All my guitars are compatible with the game (and I think any other guitar it will be probably, could be determined even a MIDI keyboard used ^^), I can only players of guitars, it open tuning or drop C / D of dissuade, and the reference on guitars with Edge III Tremolo (Floyd Rose), which in the game with 3 or 4 songs (Incubus, Muse) is tuned to Drop D and this slight mood change can already cause problems.
