Quoted from John_I:

I have a friend (with ~80 pins) who absolutely hates WOZ, so I always torture him by challenging him to a game on WOZ when he comes over. He reluctantly does play after bitching a bunch, but absolutely will not play the outlane modes. He simply walks away and lets the ball go.

Quoted from Law:

This. So much this.
I've played the game somewhere around 70-80 times at this point, and every time I start something I've not seen several times before all I can say is "The heck do I do now?". It probably took me five-six games before I got any sort of inkling on what was going on with the multiball rollovers or what I'd done to qualify a lock on the ramp. At least the ramp lock insert is well positioned and self-explanatory. I've never encountered a game before where I could not figure out what the heck was going on MOST OF THE TIME.
On top of that, the lights on and lights off BALL modes (arguably the easiest thing to figure out how to start on the table) are designed to remove your ability to follow what your current objectives are. Annoys the heck out of me.

Quoted from Law:

I may have played it at TPF once. The rest of the games were on the two ECLEs on route in my area. No idea what code version but the operator usually updates their machines soon-ish after an update is out.

Quoted from Pimp77:

Try explaining the ____ rules to someone.

Quoted from Eskaybee:

So if I'm being honest, which is the title of this thread, then no, WOZ is not fun. Took four locations to find a working WOZ and once I finally did play it (this past thanksgiving weekend), it was very underwhelming.
Gameplay was ridiculously slow and even though I liked what I've seen from the LCD screen in pictures and videos, the implementation just did not work for me and looked extremely goofy as a player.
Now this was a location WOZ, so take that as you will but the TRON and DINER sitting next to it played great. Maybe I just don't like slow tables anymore; and Keith is my favorite programmer so a lack of understanding the rules is understood on my part.
But the lighting, GI especially, was horrible and dark. Even though it had color changing inserts, the lighting was very underwhelming. It makes me wonder if something was wrong with the machine for it to be that dark. So that coupled with the slow gameplay and overly large poorly implementation LCD screen just did not give me a fun experience nor did I have any desire to continue playing but did anyhow to give it a chance and see what I was missing...but couldn't find anything, it was simply not fun.
But like I said, I'll reserve final judgement til I play other WOZs and/or a huo one. These are just my initial feelings after finally finding a working WOZ on location which took 1-2 years and 4 locations to find.
