Owned both. Really thought GB would win out but as others said the gameplay with current code is just lacking. It's such a great package too.
WOZ is becoming my favorite game period. I'm on my third and I think it will stay. Of the three I've had never had one light issue. All were ruby red.
The code on it is deep, the build quality is amazing and with so many toys AND the light show its an absolute stunner. People who stop by and have no idea about Pinball after instantly drawn to it. The game has that same special feeling the movie does.
