I've never gotten to play a prototype, and my days of preordering from a startup company and waiting on their production to finish for years are over for good.

My biggest concern looking at the design is that they are overvaluing video as a pinball hook (this happened before somewhere, can't quite put my finger on it... ).

There needs to be a serious mechanical hook in pinball, and besides the video in the playfield, what's the featured hook exactly? To me, it looks like a big wide open playfield and unfortunately your design is handicapped by nothing in the middle of the playfield in a huge area so the ball can make pretty pictures. That's a gimmick, not a hook.

Full Throttle has video, but isn't relying on it. A fast flowing design, a small screen not handicapping design, the popup wheel bumpers being the hook. FT appeals to me more from first glance than P3 does.

P3 looks very cool, but it needs more to it than a video gimmick IMHO! And $10k is going to rule a ton of people out.
