Which one is the worst pinball machine ever is really a relative question.
There are hundreds of EM machines that would probably end up on top (Even before Shaq Attack yes.
It was hard for me to remember one that I didn't like but if I take in the equation that I love Pat Lawlor designs I just couldn't play Rollercoaster Tycoon (2002) a lot.

The Addams Family wouldn't be anything special if it would be released today.
To understand why it was so special, you have to jump back to the year 1992.
It was quite a revolutionary pin at that time and they made a record selling more that 20.000 machines.
It became a classic because everybody knows it. It's still fun to play.
You gotta love the randomized magnets and banging Seance mode.

Overrated compared to the new machines? Hmm, maybe.. But.. Is the new Mustang better than the original 60's Mustang? Yes it is.
It's faster, it's more economic and you don't need to pop up the hood every 100 miles.
But it if you ask people which one they want... the answer in most cases would probably be the original one.

It's all about how people remember it. All the memories that came with it. All the good times they had while playing it in the past.
That's why TAF will stay in the top 10 for a long time.

Striker Xtreme (Stern, 2000)

I understand that this game was built at the worst time for pinball scene but releasing this atrocity was like pouring gasoline on burning pinball industry.
