Since in these breakdowns they invariably seem to be using stats collection from the games themselves, I would love to see how many of the pirated copies progress past the fist X% of the game, or continue playing beyond 24-48 hours, whatever the devs would consider around the mark for what they would consider releasing a demo for. Not that I think all the people that pirate are just demoing, but I think without quest…
Possibly they could approximate this by pushing a version update through the app stores, which most pirates presumably wouldn't receive, and then comparing stats for different version numbers.
