All good points.
I know that there are a lot of people on Gerry's Multimorphic forum that have been working on their own custom games using the P-Roc controller, so there may be people there who are also interested in making games for the P3.
We'll have to wait and see what's in his developer's package I guess. I certainly hope that lots of people jump on board, the more games get made for the system, the more attractive (and cheaper for each game) it becomes. I understand what you are saying about the obstacles, however.
I can also see how this might be easier for a group of people to create a commercial game. All you need to design is your playfield modules and the software rather than the whole machine.
As for the legs, I'm pretty sure they have changed those, they are much more like standard pinball legs now (we'll see more of the production models at Texas this weekend).
