DE GnR only covers their first album, appetite for destruction. Their use your illusions albums could support a game unto their selve. Lies is a great album that could use some theme integration.
Chinese democracy is also a good album. I think if axel would have dropped the Chinese democracy name and song, then the rest of the album would have sounded like another Use your illusion.
The spaghetti incident was a waste of time.
I like the old game, but a new one could be pretty sweet and maybe the first music pin for me.
