Aside from the games with FMV rips & the last few with down-rezzed CG work, Stern was very good at dots. Metallica & ACDC's dots had excellent & fun design & animation. LOTR, TSPP, FGY, POTC, etc - all had fantastic dots that were equal or better to B/W's best.
The problem with the LCDs so far is that Stern doesn't have the experience, talent or time to make them look contemporary. So far they look like 90's CD-ROM games. So even tho they're using a modern display, the content on it makes the games look dated...but not in a good way.
So, even tho the DMD is "old technology" - look at what we're talking about here - PINBALL, for crying out loud. An ancient obsolete game. Pinball is inherently retro - and that's part of the appeal. When people play pinball, they're not playing for the tech - they're playing for the old timeh retro appeal and fun, even if a game is new. Because pinball is retro, a well done retro DMD is going to look far more appealing and fitting than an LCD with dated transitions, animation, font, etc.
So far the only LCDs that have felt relatively contemporary are WOZ & Hobbit...but they are a bit slot-machiney in presentation. They're far beyond Stern's talent, though - but they've also had far more time to work on them.
