They're big and heavy and have a lot of wear parts that are expensive to maintain. Standing in one spot not blinking isn't great. I can play pinball in VR and have about an equally good experience these days.
My father had several of these mechanical machines during my early adulthood. It was one of the few things we "did" at family reunions, and was always worth a few hours playtime...
but damn if they didn't require a "first name basis" with the repairman, and they were absolutely not able to be transported without a team of helpers. When we sold the house most of them were "given" to the new owner [sort of white elephant?].

I could never get in to the virtual pinball machines [it's been about a decade], but I guess they "play" identical to a "theoretically perfectly-operating" mechanical type?
