Guns N Roses will probably be JJP second biggest seller of all time behind WOZ for many reasons.
GNR has a massive fan base just like ACDC and Metallica. Music pins go beyond pinball and reach out to the fans of those bands.
This game will be promoted without a doubt by the band and the members on social media. In other words their fans WILL KNOW!
Also I think with any music pin you either like the band or you don't so the game could be incredible but if you don't love the music then you're probably not a buyer. If you love GNR you probably already have money in hand. Personally I think its going to be an amazing game, and finally we get to see what JJP can do with music theme.
THIS I CAN PROMISE... GNR will be the first pinball game in PINBALL HISTORY to feature the band playing. In other words showing the real band playing songs. Every music pin to this point has never had a full color screen so you see animation... on Kiss you see dot matrix images of the band but its not the same.
This game is going to be on many levels GROUND BREAKING for music pins.
