Quoted from MK6PIN:Pinball machines in general always need some love every now and then.....NIB is WAY better than a lot of used games, however, as most things aren't women out or EoL. Suppose low-play, later releases may be an exception (bugs already squashed and adjusted). I enjoy working/ tinkering with them as much as playing them actually (when I have the time).
If you have OCD, they'll always be something to adjust, lol.....There is definitely an adrenaline surge for NIB, however, which is hard to describe (in for an LE, btw)....
I actually think used games in general are better than NIB, except for heavily routed pins. At least from my experience there is always issues with NIB, while used ones have those taken care off by the owners. You get them for cheaper and usually with mods too.
As an engineer with OCD, I spent hours modding a mod for the chopper blade on JP to make sure that it spins juicily and properly synced with the sound from the game. When I told the mod seller about this, they mentioned it's the first time someone having this issue. I doubt most people pay attention to the movement of the blade vs the chopper sound.
