Please spare me yours.
You are lumping together everyone who pirates into the same group, which is ridiculous, people pirate for many different reasons, pre-release leaks, trying it out first, cant afford it right now but may well purchase in the future etc.
Im not trying to give you legitimate reasons for pirating, and im not trying to make out that it is legal or morally acceptable, but when you lump everyones reasons for doing it into one group, you are just as bad as the people who try and rationalise their decision to pirate.
Ive pirated games, sometimes for DRM reasons, sometimes because I wanted to get a true look at what they are like (Demo's tend to pimp only the very best points of a game and are hardly representative) but I also buy a hell of alot of games. Im not trying to say that pirating games is acceptable, im just saying that you are overly generalising, and it makes your point laughable.
