No disrespect to Slayer or to you intended, but Stern will only work on legends of rock for their rocked themes games. These pinball machines have to sell in large volume inside and outside the USA for Stern to invest money into making one. Stern is a business that needs to make money to survive.
That's why, eventually, we will have a QUEEN pinnie. Apart from the Beatles, there is no super-mega-world-wide-legend-band that will sell more machines that a QUEEN themed machine. QUEEN are massive all over the world and especially in Europe and Asia (Japan in particular).
The bands with the most album sales of all time, according to https://en.wikipedia.org/wiki/List_of_best-selling_music_artists, are (in order):
The Beatles
Led Zeppelin
Pink Floyd
ACDC
Queen
The Rolling Stones
I'd love to see a pinball machine for each of the above. I would buy a pinball machine for each of the above, except maybe Pink Floyd. Only one on the list is from the USA. But that's the list Gary should be looking at (and has in the past with ACDC and The Rolling Stones).
Wouldn't these be amazing:
Sergeant Peppers LE
Stairway to Heaven Premium
and
Bohemian Rhapsody Pro?
