They havent copied anything from anyone in 10 plus years
Do ya think that might just have something to do with the fact Williams left the industry 10 plus years ago and there's been no-one to copy? :)
Seriously, Stern are the absolute MSMD, it goes back to classic Stern copying the Bally boardset and then DE copying the System 11 boardset. Never been anything but imitators, and now they have been left on their own for 10 plus years have failed to innovate, and will be forced to play catch up footy with JJP.
This isn't to say they haven't produced few really good games in their time as the only manufacturer. But they haven't done much to move pinball forward.
Really think the LCD idea has some great possibilities.
