I find WOZ to be similar in playing style to TZ, so if you're wife wasn't blown away by Spiderman and likes TZ, I would venture to say WOZ would be a good choice.

There is so much stuff in WOZ and it is really polished in terms of code, LCD and build. However, it's gameplay is not for everyone. There are many ways to approach the game. My machine is set-up somewhat steep and the exposed pop bumper and witch magnets rocket the ball around. It can be brutal at times.

For those that only like games where most shots return directly to the flippers allowing them to combo ramp and orbit shots, WOZ is not a good fit. WOZ is plenty fast but doesn't have that kind of flow.

That's not what pinball is all about for me. Don't get me wrong, I love games that have that kind of flow, but I also love games where I need to get control of the ball, figure out what shot I want to hit, then hit it.

I find my adrenalin is really pumping when I've got two multiballs stacked and I'm trying to get a crystal ball mode started while also trying to get both upper playfields going simultaneously on WOZ.

The OP didn't say if he had other games in his collection. That would make a difference. I think when it comes to toys and sheer amount of stuff in the game, WOZ wins hands down. If the OP has mostly loaded games with TZ style of play, maybe a good flow game would be a better choice. If that's the case, there may be better options than GOT, perhaps ST or AC/DC if it must be new or recent. Lot's of great older games if used is an option. STTNG and LOTR are two of my favorites.
