I will say this as politely as I can, clearly indicating that this is my personal opinion and not fact, and is a subjective statement in the purest of possible forms: This is a pretty terrible list of games, for me. Financial considerations not in play (of course I'd trade my Bow and Arrow for a WOZ and take my girl out to Old Homestead for steak) there's not a single game on that list I'd trade for any of my 15 games. These just aren't my cup of tea.
That being said - and many people have said many bad things about most of these games over the years - Balcer would seem to be the anti-Jpop. He churns out unremarkable playfields but does them within the proper context of a project, on time, on budget, and to the benefit of whatever project he's been drafted for involvement.
For American Pinball, this very well may be enough. Their time with Jpop wasn't without benefit - they learned some very important lessons about pinball design, pinball designers, what the new breed of "collectors" will pay for and get excited about, and what it takes to get a machine out the door. And, WOZ proved that if you stick enough Jpop-style flash in a Balcer game: magnets, bright lights and colors, innovative display, "magic," and gimmicks, then it's really not that important what your playfield is like as long as it functions correctly and showcases the gimmicks. So, take Balcer, and add some classic Jpopisms like Escaping milk pop bumpers, a shitload of magnets, and real quickstep solenoids, flash it up with a bunch of blinky blinks and additional gimmicks, and it may well sell.
I really didn't know who Balcer was before he was hired by AP (as I said I've never been a fan of the games it turned out he was involved in). But clearly, he could well be the right guy for this project. They were smart to grab him, especially after their experience on the other end of the spectrum with JPop.
