Mind you, I'm not suggesting that the piracy be ignored...
None the less, the question becomes one of whether or not the sellers of legit PDFs are making enough money despite the piracy. I'd dare to wager the following:
However - those who end up not caring initially about Traveller, and become hooked on a pirated copy, will also probably be like the rest of us dudes... they will wait with eagerness for the next NEW installment to come out, and being the impatient sods they are, actually PAY for the copy to enjoy the priveledge of having it faster.
Net effect? Perhaps (note: I say perhaps) a little extra in sales.
ah the old Internet Piracy Debate .....
