Just weighing on this one and for me it would be WOZ as it did bring in many new innovations that are present in all the newer games. Do not own it but have played it numerous times and was always a fun pin even with the stop and go that permeates in game play. I have so far just a small group of pins( AC/DC, MET, MBrLE and soon MMrRE)
That being said AC/DC was the game that got me into the hobby as my first NIB pin. When I saw the ads for this it became a must have and at the time the pricing wasn't bad. This game has a ton of flow and sadly is now my least played pin. From a fun factor and just want to bash the ball around MET is one heck of a game.
Looking forward to the next decade of pins!!
