A point of view:

The study may indicate that pirates as an aggregate group, in addition to pirating stuff, buy more stuff legitimately than non-pirates. However, that is not necessarily applicable to an individual case and especially non-applicable to a niche market situation.

The study also seems to focus more on music and video piracy, which is a rather different situation than an independent game publisher. When you have a mass market of hundreds of millions of customers, the impact of even thousands of pirates is not going to have a big impact.

That kind of numbers obviously don't apply here, so that study, for the purposes of this thread, is completely irrelevant.

Hopefully we can now close that tangent and discuss the free to play games and their various incarnations.
