innovation of Guitar Hero 4 is going to be the creation of custom tracks, among many other things. Coming to us courtesy NeoGAF is the news that the game will include three instruments (but no lyrics), drums, bass, and vocals guitar. Not only that, but GH4 is also going to include a form of file sharing allowing you to share up to 5 different songs (more if you're rated higher) to "GH Tunes" for anyone to download. Included in the download would also be the custom title, creator name, and custom album art. And allowing for even more personalization, the game will also have customizable rockers and instruments.
And that's not all either, Neversoft has also confirmed that Van Halen, The Eagles, Linkin Park and Sublime will be making appearances, and that the GH4 controller sports some sort of new input device. With so much change coming to the franchise, and so much emphasis on custom content, is it possible that Guitar Hero can survive in the world of Rock Band?
