And how would they know?
Well, I'm not a very good liar. I would eventually out myself somehow.
Plus I don't think I could really enjoy the game know what I had to do to get it.
What? Why would you lie? Unless you suffer from severe tics, making you shout out "I PIRATED A GAME!" whenever you're nervous, I don't see why you'd ever have to lie. "Did you pirate this game?" is a bit of a random question to pose to someone for no reason.
Especially if you've already bought the game, regardless.
As for what you "had to do to get it"; You make it sound like you'd have to shiv a man to prove your loyalty to the pirates.
