Good post!
I've stated before how impressed I am with WOZ.
The biggest problem out of the box, from a gameplay perspective for me, was the GI lighting. Just terribly dim.
Unfortunately, that's the way a LOT of players are first experiencing the machine: at shows, at friends' unboxings, etc....and walking away from the machine with an opinion, usually negative or neutral. And mainly because they can't see the playfield and aren't used to playing with that kind of dim/high contrast lighting!
It is night and day, literally, with the lighting kit. You can actually play the game in the dark! I'd prefer a green strip on the right side and a blue on the left (instead of the blue all the way across the back), but apart from that I highly recommend the Pinball Lighting WOZ kit. Makes a world of difference in the enjoyment of the WOZ experience when you have a bright well-lit playfield you can follow the ball on. And it helps balance out the extremely bright insert lighting.
It's such a game-changer that you seriously shouldn't cement your opinion on WOZ gameplay unless you've experienced one with a light kit. It's a ball control, sharp shooter's game....and a bright well-lit playfield is absolutely required for enjoyment. (I personally can't believe JJP went forward with a GI system that ridiculously dim, but considering it can be remedied with $100 and about a half-hour of your time, and taking into consideration all the other things which were knocked out of the park, it's a small complaint and easily remedied.) But I really want to drive the point home for those whose WOZ opinions were formed on the original dark playfield with eye-scorching high contrast inserts where you can barely follow the ball during certain stages! Play it with the lighting kit installed and it's a whole new game!
