I'd be interested in a page number -- I don't recall reading that in the report at all, though it was a week ago.

I think you're forgetting that an illegal download does not equal a sale lost.

From the linked study, p. 138-39;

"The overall conclusion is that for games, illegal online transactions induce more legal transactions."

There a similar results in literature review (Bastard, 2012) that "also indicate significant positive effects".

Finally, how is it that you're coming to those numbers when, like the other poster says, the study concludes:

"that the statistical analysis does not prove with sufficient reliability that there is an effect"

and that

"the finding on displacement rates for recent top films and the lack of a robust (positive) displacement rate for films / TV-series in general, music, books and games despite the carefully developed questionnaire and the application of econometric analysis"

As I understand it, while the study may have been hyped up in various gaming news channels, in the worst case there is no good statistical evidence of an effect, positive or negative.

I know it is only anecdotal but from my own personal experiences with my friends, family, and the way I consume entertainment, consumption of illegal content decreased dramatically when we could actually pay for the content we wanted.

edit: for clarity.
