Activision CEO Bobby Kotick said in a MTV interview that “[their] version of ‘Guitar Hero’ generated far more in revenues than any Aerosmith album ever has". Says Kotick: “Merchandising, concert sales, their ability to sign a new contract [have] all been unbelievably influenced by their participation in ‘Guitar Hero.’"
This was also confirmed to CNN by game creator Kai Huang: "Aerosmith generated more money on royalties for their game ["Guitar Hero Aerosmith"] than they did on each of their past two albums. So they [the games] are truly bringing artists to new audiences, and much bigger audiences."
Metallica - whose complete latest album was released for Guitar Hero 3 - are also expected to be featured in their own 'Guitar Hero' edition in early '09.
