Well, that's like asking why buy games in general, when often most buyers here never play them to begin with. So I don't know that logic is really the order of the day around here, but to each his own. And I didn't say anything about pirating anything, as it would be easy enough to swap the games in the unit, for the "English" equivalents, and not really be stealing or pirating anything.
Once again, the end users choice. I'm sure some will, and some won't. The same way some pirate games now, while others don't, I was merely pointing out ones options, and nothing more.
EDIT: I'm also pretty sure that most people who are willing to pay money for what is pretty much an emulation device, with "N" branding on it, already have most of the games offered in many forms across many devices. So once again, I don't know that anyone would be pirating anything.
