I picked up #349 from the FedEx hub on Friday (I could have had it delivered Monday, but who wants to wait?). The build date is listed as 1/11/2019. Melissa told me CGC contacts them as soon as a machine reaches the plant dock.
Out of the box the game plays perfectly. The flipper power is set to -6 based on comments posted here. The neighbor who helped me get the game into the basement was over yesterday and I couldn't get him off the machine! He has helped me move games in the past and MBR is clearly his favorite.
An issue that I found prior to playing involved the playfield. While waxing, I noticed multiple areas with 1" diameter haze spots in the clear. This is typical in the auto industry when defects in the clear are removed with a super fine abrasive, that is what I suspect happened here. I used Novus 2 and a small orbital buffer to remove the marks and now the playfield looks perfect.
It was a minor PIA and something the plant should have caught, however I am very happy with the game and glad I did not jump ship. Having participated in purchasing a MMR LE, I am more than familiar with everyone's frustration and understand why you would want to bail. However, if MB is a game you have always wanted, CGC has knocked it out of the park. Let them correct their playfield issues and keep in mind that it wasn't too long ago that people thought this machine would never be made again.
