People can always make copies of a game and then pass the working code key with it. Clearly what the people on this site are concerned about is illegal, or they would not require having confirmation of sale (however you do that, anyway). But if you have a pirated copy, you probably will make sure that you have a working key, or if you are making them you will publish them with a working key. And I certainly know the difference between pirated software in the marketplace vs. legit software. If it is not legit, i won't buy it, out of concern that I will get a bad copy with bad security, much less the fact that its the wrong thing to do anyway.
If you have the authorization to pass out the key, and that is it, thats fine. But the people who made the game should do the right thing and make the code public. That way they can give back to the players who have already paid their money for the game, but can't play it because of THEIR error.
By the way, do you still email frey? I sent him one a couple of days ago and have not heard from him. He's either busy or not comin' round no more. Is there someone else to contact? What proof do you need. I have the box, the little folder and the book...
