If I could have just one pin, I'm confident this would be it.
When I originally played it, the game was heavily routed, lit poorly, un-level, and there was so much going on - it didn't make a great impression (how many games fall victim to this I wonder)
One day out in the wild, I happened to find a better example and had a completely different experience - the game started to click but I didn't have any idea just how much it had to offer until I decided to purchase one for myself and set it up the way I like.
What can be said that hasn't already?
lasting play-ability, sounds and music, dots, tons of shots, theme integration, modes galore, wizard mode, gumball and upper playfield, powerball , magnets, diverters, wireforms and ramps, hidden shots, 4 flippers, lock shots and scoops, a working clock.
This game is what happens when a genius crew had carte blanche in the heyday of pinball. When set up correctly, TZ embodies everything that is great about pinball.
If you've found it slow or poorly lit - don't fault the game, but the operator.
TZ is fine for casuals, the theme recognition isn't there for younger generations, and it's really best experienced by decent players looking for a game that will take months/years to appreciate so consider that if thinking about adding it to your collection.
I don't think I'd be able to part with mine, and it would be the last to go - it's that good.
