My daughter and her boyfriend played Humpty Dumpty split flipper, and were desperately trying to "roll" it. It displays the score using two lights: one behind the 100s of thousands, and the other behind the 10s of thousands. The 100s of thousands only went up to 700,000. So the highest score it could display was 790,000. They managed to get 770,000. We have no pic of it, however, as they were so confident - they were waiting for the 790,000.
I loved Houdini. I think the 15" display in the backbox is brilliantly done. It shows true innovation to NOT follow the trend toward putting the largest display possible into the backbox.
I also liked Aliens. There is a mode where you are supposed to hit certain shots (highlighted one color), and avoid other shots (highlighted by another color). I think you were trying to find Jonesy the cat, while avoid the Alien's acid. I thought that was clever, and a good use of color LEDs.
I think Lexi Lightyear and the P3 system was well done, and very innovative. The ball tracking was slick. However, I wonder if the video playfield will ironically be an achilles heal. Will the novelty wear off when the video starts to be compared to video games instead of other pinball machines? Right now, it compares favorably. But when it becomes a bit dated, will it transition to being seen as "retro"? I suppose that will be determined by the quality of the actual game play.
