Cheapest Blu-ray burner: $180 or so Blu-ray discs: 10-15 for $30 (I think) Electricity: A buck or less per day On the high end, after 30 days of downloading, that's $240 for the first 15 games, assuming all the discs come out okay. New releases are what, $60? That's $900 for 15 legit games. The next batch of 15 pirated games would be $60 for the discs and electricity on the high end. Also, if a person is pirating a PS3 game, they're probably also downloading other media, meaning that their system is probably on when unattended anyway.
