Or to summarize the post above mine: "You only refuse to pay because you are able to get it for free. If pirating were suddenly 100% impossible, would you still refuse to buy, and instead never play another game again because you still don't intend to pay?"
That's a good summary, and the answer is no, but since Sonlirain's post misunderstands me, it's not a refutation. I don't refuse to pay for video games. There are plenty of video games I bought and never would have even considered pirating. Likewise, there are games I pirated that I never would have even considered buying. If there were no option to pirate Sleeping Dogs, I would have gone without.
I think the key to "beating" piracy is multiplayer. If a game has good multiplayer, I'll buy it, since multiplayer generally doesn't work with piracy. I'll probably get NS2 if it goes on sale, and I haven't even considered pirating it, because there is no single player. I preordered Dark Souls, never thought I might pirate it. Again, because multiplayer is what makes it. I think game companies are figuring this out, they're just not doing a great job of it yet. All these preorder bonuses, purchase bonuses, online components, the intent is to provide features that you wouldn't be able to get (As easily, in some cases) by pirating. It's just that right now a lot of them suck.
tl;dr: If you want people to buy your game, instead of trying to force them to do so, give them something they can't get through piracy.
