[quote name='kklems']This game is only played by using the GH metallica disc right? ie no code to download and incorporate into larger guitar hero game (unlike rock band ac dc which allowed you to import into RB1 and 2) If that is the case I am happy to wait.
And on a note about Metallica I am not to thrilled to support the greedy sobs. I was a huge fan back in the early days and they supported their fans until they got big and than Lars et al got greedy. They seem to forget how so much of there fan based happened by word of mouth versus radio play. Heck they even released a vhs tape with nothing but fan footage of their shows. I am all for the artists getting paid but Metallica seemed to forget where they came from.[/quote]
I'm currently renting this game. As a Guitar Hero-turned-Rock Band player, as a Metallica fan, and as a Thrash/Heavy Metal fan in general, I'll answer both questions...
1) No codes are provided with whatever. The only thing you'll gain from World Tour is the Death Magnetic DLC. Activision never made their DLC backwards compatible since GH2 on the 360. For Rock Band, it was psudo-revolutionary to take nearly all the content from one game and make it compatible with the future game.
2) I can agree with you on the Greedy thing, however if you actually played it, there is a lot of work done with this game, a lot of effort put into it. The character animations are some of the best in any music game. "Metallifacts" provides interesting details about many songs/albums/musicians I didn't know much about. 99% of the setlist is all Heavy Metal. There's plenty of videos (over a dozen bootlegs, behind-the-scene vids, etc.), a much easier progression of career mode, and easy achievements.
I don't wanna sound like a sadistic fanboy, but at least give this a rent if you're a fan of guitar hero and heavy metal.
