I wouldn't be interested in single-band games from any
band, not even my favorites. It'd get too monotonous, and I think a big part of the appeal of the series is the variety of all the different bands and types of music. I'm not saying I wouldn't buy a Metallica game, but definitely not at full price--$20 or $30 tops. I'd really rather have all that stuff as downloadable content and not separate discs.
That said, this got a bit lost in the shuffle in all that news last week:
As fans progress through their careers in the game, they can rock out to scores of Aerosmith’s greatest hits, as well as songs from celebrated artists that the band has either performed with or has been inspired by in some way.
Now what exactly that means, as far as ratio of Aerosmith tracks to non-Aerosmith tracks, nobody knows at this point. But that makes it a little more appealing, to me anyway.
(And Brent, you're not missing much with "Dream On." It's super-easy and it's a 2007 re-recording, not even the original. And on that note, I've heard that all the old 70's masters may be lost, so it could very well be that whatever "classic" Aerosmith tracks we get in the new game may be new re-recordings.)
(Although, "Same Old Song and Dance" was the original master track, I do believe. . .)
