Didn't Nintendo confiscate copies of Pokemon XY that had the street date broken? I would fear Nintendo ninjas too much to actually do anything.
I think that was because they were gamestop employees, so they could?
Yeah, they were dumb and basically revealed where they got it from.they fined the store $5000 (iirc) for every copy they couldn't get back.
If some guy got a copy, played from home, didn't show his sources, how would nintendo know?
