Build a system where you can install a default program that runs a basic game:
3 ball game, trough support for optional multiball
Flippers already set to go full force for half a second, then run 25% hold
Both Slings fire

Allow easy variables for:
Assigning wait values for specific solenoids
Assign bonuses for combos
Assign extra balls
Assign multipliers
Make it super easy to assign point values to switches, randomize sounds attached to those switches

You do all that, and you'll finally see every serious hobbyist attempting a custom pinball. I personally think P-ROC is a huge barrier to entry from everything I've read. Most of us don't want to learn programming, they just want to build pinball and choose options.

Honestly, if a company were to supply a kit where you have a basic whitewood playfield with flippers, trough, slings, and a shooter lane carved, and everything wired up to shoot into emptiness (can start fabbing a layout with foamcore right away), and a 64 lamp matrix controlled easily with software (when that builder is ready to start laying out inserts) it would sell like hotcakes.

That's what I meant, that barrier to entry is learning to code in python, not so much P-ROC as a product. Most of us don't know how, and I think most of us don't want to learn (maybe some of us aren't capable of learning). I also realize if I want advanced modes, someone is eventually going to have to program it (can only make it so simple), but if you manage to create what is a pretty fun layout, there could be a programmer that would jump on board to help.

What I'm talking about is I think probably 90% of pinball hobbyists who want to build a custom pin; don't even attempt to build one because there are too many skills needed to create one. There could be a lot of people with good ideas who are capable of fabricating a playfield, maybe even have artistic skills to do the art for a playfield, but then look at the programming portion of it and give up. Having a basic program (and I haven't looked into PROC enough, or at least haven't looked at it in a while to realize there is a basic script) that ran a basic game with assignable point values from switches would probably encourage a lot more people to create their dream themed pin.

I also think $900 is a heck of gamble for a P-ROC system, and it sounds like much more cost effective systems are coming.

I'm just basing it on an earlier comment from horsey of $942.82.
Bear in mind, I don't think your prices are outrageous, I just think it's possible to build a slightly less featured system for less. I DO think the open source you've opened up (being the first) is commendable.

If this is really true, you guys have done some amazing work.
