Played it at Expo, was fun to play. Hard to judge a game when it is not leveled and setup like crap. I mean, there is no fun pin no matter what if it's setup bad.
The layout is pretty standard, GotG, Met... It's got some cool mechs, they added some modes, songs, callouts, revamped the art and you get the LCD with live footage.
Is it a new revelation and pushing the boundaries of pinball, no. But it's a very nice refresh on Metallica and stern saw they were leaving money on the table when people were reselling the original Met at higher price vs msrp... So I guess this is a win for them and the people that wanted a Met,but didn't want to pay above NiB price. Not sure it warrants a full replacement of the OG one if you have one, but can't say since I never owned one.
