That's the way everyone should see piracy. Me? I'm a pirate. Do I purchase games, music and movies? Yes, the ones I liked. How else am I gonna decide whether or not to buy a game that lacks a demo?
If you go to a car dealership and ask to have a test drive they won't call the cops on you, calling you a thief. Instead, you actually get to have a feel of how it drives, and then make an informed decision.
Same thing with games, go for a spin and buckle up the credit card. Or erase the whole damn thing and torch it so it doesn't come back to haunt you in case it was horrible.
Not all pirates are the pillage and burn them type, some of us just want to find a sweet game and then show our gratitude by actually purchasing it.
