I'm not sure why the backs aren't there other than my graphic designer is always looking out for me (cause he's an awesome guy) and it was probably a measure to prevent black market manufacturing (this is a real thing) I will always make a PnP for every game so people can play it.
I figured this would be it. The quality of the PnP files for Pay Dirt is higher than anything I've encountered before, so obviously something had to be left out to encourage people to get a proper printed copy of the game.
On a related note: Patrick, for a future project you might want to consider including a low-ink copy for those who are less keen on printing full-color page after full-color page. That should help getting more PnP copies out there to promote Crash Games' products.
