It can be hard to capitalize the R&D costs that went into games like TZ, RS, etc, without having higher prices like WOZ.
It is a toss up between the needs of the market.
Ops, that need cost effective machines to get a return on Investment.
Themed games. that have costs in licensing.
and Regular players/owners, like here on Pinside, where we all have unique tastes.
i too, would like to see things in Innovation. Be it toys, motion sensors, fiber optics, under playfield grid sensors,
even troubleshooting...like WOZ, or Capcom years ago.
All it takes is money, and a market willing to pay for it.
They make decisions now, to be profitable, and to keep people employed at a wage that is competitive.
Id be confident in saying, that no matter what they do, there will always be a "taste great, less filling"
debate.
So for the Op, that isnt a fan of Sterns, and we have many here in Florida, and have had this discussion many times, the answer is for yourself...dont buy them or play them.
But most others are here to disagree, and few would take an arm chair critics position to suggest that the company should change to fit the minority in their needs.
If they can profit from a remake, as we see now, and licensing works, then for money, it will be done.
But other markets do want new, and it seems to suggest they abandon that wont be happening anytime soon.
