Quoted from TheLaw:An unknown company halfway around the world, with no real guarantee they could get it done, offered a classic Bally and everyone rushed to pay over 7K for it day 1.
Sure, and if Stern were to find itself in the position of not being able to sell their stuff, maybe they would try it.
But right now, they have a huge backlog of $8-10K games that they can't build fast enough. They have no incentive (or additional capacity) to build cheaper games that they'll make less money on.
If operators stopped buying Pros because the economics of location play aren't working, Stern might try to start stripping down the Pros even more than they currently do. At that point, a single level old-school game might make some sense. But it would probably be easier to just build something new than try to recover some old design (for which the operators would have no special attachment to anyway).
