There are early indications that Guitar Hero III has had a significant impact on record sales for bands featured in the game.
The game, subtitled Legends of Rock, was released in the US at the end of October. It will launch in Europe on 23 November.
Hard rock label Roadrunner Records said that sales of DragonForce's album "Inhuman Rampage" increased 126% week-on-week in the wake of Guitar Hero III's release. DragonForce's song "Through the Fire and Flames" is featured as an unlockable bonus track in Guitar Hero III.
