To my mind, there are alot of excellent games in that production list that are far better players than alot of the over-rated later models of B/W.
But everyone will have a different opinion. I just try to look at the positive things Stern have done, because no pinball company is perfect ofcourse.
Stern have done something no other pinball company could do, that is STAY OPEN and producing. A monumental effort.

Recent offerings like AC/DC and X Men are excellent. Many in the earlier years are great games as well. There are many great players in that list.
Inventive is a hard one to talk about, because inventive means moving parts, and moving parts/toys/features need servicing and cost more to maintain. These days, inventive usually covers better dot matrix annimations and better audio with better gameplay n code. A game doesnt have to have a million bells n whistles to be a great player. The PRO machines are great value for money and are usually bullet proof.

I am glad STERN has done what no other company could do. Produce 3 or so titles on average per year for 13 years running. There is something in that list for everyone to enjoy.
