I had no idea people actually did that. I was actually shocked when my older brother rented NBA Street 2 from Blockbuster for the PS2 twice and thought doing that was illegal (which it wasn't since it was paid twice). It makes me kind of wish I had done that with Worms Armageddon... but then again, it was over a decade between the last time I played the game and bought it on eBay (August, 2014) so it's not like I would have been old enough to get away with it anyway.
