This may be of interest to enthusiasts in comparison to games built in the past.
Read to understand the relevance regarding this situation.
To my knowledge the heaviest pinball machine ever made, not counting games like Hercules or Bigfoot, is Caveman (Gottlieb, 1982) due to the extra CRT monitor offset in back of the game, extra video boards and panel, and significant amount of metal such as the specialized lockbar and controls. It exceeds of the weight of games like TZ, STTNG, RS, CV, GTB SS80s (HH, BH, MGoW, Volcano), upright pinball games, Pinball Circus, and even most intricate of complex EMs, and is well over 400 lbs.
I cannot remember the weight, but it somewhere in the 450-475? lb range (unboxed), and man is it is a beast to move.
The game that comes very close is Wico Af-Tor, with their monstrous all metal contruction of the cabinet and backbox, that never falls apart.
The Caveman cabinet never split, even today, even with glue delamination, and it was double seamed and fully miter jointed, metal braced, not just wood glued, which looks to be what is happening right now.
Tough stuff of the past.
I have even seen Caveman lightly dropped, and it turned out ok.

No pinball game was ever designed, however, to "last forever".
Most were designed to be in operation on routes only 3-5 years.
EMs almost never split, unless they get wet, except for the weak points on the back panel (particle board such on GTB EMs of the 1970s), or the bottom board (very thin plywood, not particle board) starts to finally fall apart due to the edges, but even then they have a reinforcement bar across two points to hold the mechanical board in place, if it does. The rest of cabinet on the corners, still stay together.
There is basically nothing in the bottom lower cabinet, and now hardly anything in the upper cabinet as well in modern games.
Modern Stern games are not even using a full crossbar, and relying on a particle board bottom to hold up weight (not a very good design).
Therefore, there is no added structural integrity.
Modern games do not even come close to ANY these weights (which I assume is why they do not use a crossbar), and most are under 250 lbs (unboxed, unpalleted, and/or uncrated).
The Spike system reduced entire game weight another 25-30 lbs, both from wiring, boards, and other basic game functions.
Essentially, back to the lighter EMs games of the 1960s, but usually lighter even with all the topside playfield features.
Lighter games mean more stress on joints, when games are moved or slid without support, only because it easier to move the games without proper leverage, and the cabinets have no direct reinforcement.
Anyone tried to move a particle board bookshelf without removing the books beforehand?
Now, you see what is starting to occur, at least from several directions of shearing force alone.
Another tough day at Stern, since people continue to disagree that there have been no reduction in quality or features, anyway.
My only recommendation is new owners start immediately stocking up on BLY/WMS leg bolt plates (that do not fail, but do get bolt stripped due to soft metal sometimes), and installing them when they get their "new" Stern games home, and break out the wood glue and corner clamps (or make some from scrap wood). It will be easier than "contacting your distributor for a new cabinet"?

These are some of the "basic game features" that were removed quite some time ago.
I cannot speak to the point, if an owner moves/installs a game improperly, without a dolly, thereby "dragging" or "pushing" the game across a floor, carelessly, or there is excessive nudging, which may be some (but certainly not all of concerns) the responses by Stern back to an owner. That increases the chance of immediate damage.
I installed proper leg plates on my MET PM in 2015, and have not had any problems, but I did it as soon as I removed it out of the box.
Granted, I do a lot of "bulletproofing" on my games.
Retrofitting games to prior direct industry standards used before 1999 is probably not the preferred option for new owners.
Best of fortune.
