OMG, all these complaints about putting their money out and not receiving the instant gratification of a game on their driveway are hilarious. You are all apparently newbies to the hobby and unaware of the recent history of pinball.
When Wayno announced he was going to produce a remake of MM we waited over two years with him sitting on our money and he never produced the game. He finally sold out to PP and they produced it after almost another two years. Some people never demanded a return of their money and got the game from PP for the original price of $5500 or something in that range after nearly 4 years of waiting.
And then many of us gave Jersey Jack $6500 in advance to get our original WOZLE games. I think there were some steps of getting to the full amount, but regardless we had a bunch of cash out there for 2 1/2 years. We basically fronted him the money to start his company and he promised those of us who were so loyal that we would get discounts on future games. Well, the discounts never happened.
So quit whining that a legitimate and established company is a month behind in getting your game to you so that they can take care of quality control issues. Be glad you are not getting a game with no code, cabinets that are actually falling apart and chunks of clearcoat the size of a quarter peeling off your playfield. If you can't handle this you should really get out of the hobby or just keep buying nice used games to freshen up your collection. You would lose less money doing that anyway.
