I think the problem is that Stern could've built the "topper" into the backbox. If the backbox "Kiss" just has a few std leds behind it then its mundane for today's technology, & for a band like Kiss. So to get the functionality that should be built into a game of this calibre buyers who already have spent $8k to $11.5k have to fork out more if they want interactivity. When the game is switched off then Kiss & Kiss at the top looks like they ran out of ideas (same really when on). There are 100 different things Stern could have done. The smart guys will come up with a backbox mod to make it "dazzling" & interactive - & probably $100.
Topper aside, nice to see these p/f racked up:
