Metallica Pro was my first NIB. Heck, it was my first machine! I love it. I have a GB Pro on order after playing it at TPF and MGC and can't wait to get it.

In some ways GB is the antithesis of MET. You gotta work pretty hard to get modes up and running on MET. MET also relies on heavily on multiballs. GB currently is short on multiball (which is fine with me) and encourages you to fire up modes to get scoring rolling.

They both have a heavy emphasize on "collecting" to progress the game. Whether it's snakes or ghosts, it's all good!

While I am okay with Metallica's music, my wife is not a fan. Therefore I changed the tunes that soft-rock the house! Meat Loaf? Check! Cake? Check! "Fool in the Rain"? Check!

I also switched out some of the callouts with clips from the original Star Wars movies. When Sparky gets fried, Han says "I thought they smelled bad on the outside". It works on so many levels!
