I wouldn't go near a Hendrix machine, he has his place in history but not on a pinball machine.
I couldn't see too many other bands pulling big numbers, even Iron Maiden, as cool as it would be, could not compare to the numbers that AC/DC and Metallica are going to end up producing. I don't know if a bit of a mixture of bands would be worth considering e.g. Iron Maiden, Black Sabbath, Pearl Jam, The Offspring, Faith No More, Soundgarden, Motley Crue etc etc Work your way through the ages of rock as a bit of a rock time capsule.
Even if Kiss was more expensive due to licensing costs it would still sell big big numbers.
If acdc,the who, metallica, stones, kiss, elton john, dolly parton ...geez even gnr for gods sake can be immortalised on pinball machine and not hendrix there is something very wrong. One the greatest musicians ever!
Bring on a Voodoo Chile or Purple Haze LE wih some crosstown traffic multiball action through some wicked ramps and subways!
Sweeeeeeeet!
