You try it on. For five minutes. That is hardly equivalent to playing through a game for a reasonable amount of time.

Lets face it, you and all pirates are trying to justify somethign that in the eyes of society is morally wrong. I'm not going to get sanctimonious about actually pirating (although I am going to sit here with a stick and poke holes in any argument I can), I've done it before (I no longer pirate, everything I have now is legitimate), but never once did I try to come up with pissy justifications for it.
