I own a Premium and it's a lot of fun. But for the first couple of months of owning the game, I initially felt disappointed.
But I kept playing and learning the rules.
Suddenly, the game really opened up. You can have nearly continuous multiball all the while you are building up your record sales and completing tours. The game just keeps flowing. And the music and light show really enhance the experience. I don't consider the bashing justified.
If you are considering one, get it now before people begin to appreciate this game in a few years. And work at setting it up to your liking to get the most enjoyment.
And no, I wouldn't trade the Premium for a Rob Zombie. I enjoy music themed pins but I only would consider a Rob Zombie in addition to still owning the LZ. Not even sure I would even own a Rob Zombie because I find games like Metallica far more enjoyable to play.
