Quoted from CrazyLevi:

It's time to give up on this one. The game was like 10 percent done.
Take it from Pat himself...
"That was what you saw, but the game was just a whitewood. It was a minimum of two months away from even going on test. Those internal whitewoods aren't even finished mechanically. There's stuff that isn't even on the game. The game is not complete. The software is not complete. That seems like an insignificant thing to some people, but the game is in such a rough state ... we had barely gotten to the point where we were able to play it ourselves! There were three people working non-stop on video and the stuff you were looking at was maybe 10% of what was gonna be in the game. We has scads of art that was yet to be digitized.
"That game (Wizard Blocks) is what it was when we got shut down. But that's all it's ever gonna be. It will never be completed. There is nobody currently who has the wherewithal to pick up and build Pin 2000. The amount of manpower it takes to do it is so astronomical. Here's an example: I now have a normal game team ... an old-time game team ... which means to me that I have a mechanical engineer, a couple of software people, an art ist, a sound and music guy, and a dot matrix artist. That's a core game team that works full time from between nine and twelve months to produce a pinball machine. You take all their salaries and you come up with some number and say this is what it costs me to develop that game.
"A Pin 2000 project immediately doubles that number of people. It becomes a combination video game and pinball machine. It's like taking a Midway game team and coupling it with a pinball game team. You have an immediate increase in overhead and an immediate increase in the technological level it takes you to pull it off. There are people who bandy about this idea that you could somehow just buy the patents and build Pinball 2000. The amount of technical expertise is huge.
"First of all ... you can't build Pin 2000 the way it exists because the electronics that were in the Williams version are no longer available. You couldn't even reproduce them. The board that ran that system was a consumer product that is no longer available. So you can't just take the bill of material and turn on the assembly line. You'd have to re-engineer the whole video portion of how that game works. Could it be done with enough money, sure ... but is a company willing to take all the manpower and the year and a half to start up and do it? My humble estimate of what it would cost you to pick up the project and try to run with it again is a minimum of two million dollars. That get's you the first game to the assembly line."

Quoted from Aurich:

SWE1 is one of the few pins I've walked away from without finishing my balls, though to be fair it was set to 5 ball, and I just couldn't take anymore. Only other one I can think of where I did that was Varkon.
