The idea that bitchy DRM is what you need to make money is silly. The bitchier the DRM, the more it costs you in terms of implementation and support and, guess what, it turns out that a great many of those pirates just won't buy your game, they don't want it for anything more than free.
You can see some good examples in the audio industry, which has some really bitchy DRM. Like take Steinberg Cubase and Cakewalk Sonar. These are two of the long time DAWs, both dating back to the DOS days. Both still make money, both are still in active development. Cubase uses super retarded DRM. A dongle that Steinberg bought and customized (syncrosoft, now called Elicenser) that is checked when you do anything. Seriously like opening menus has checks to the dongle. Sonar has no DRM effectively. You need a serial and an activation code, but the activation code is per serial, not per computer. It is just so you register your product with CW. The serial and code don't change and it doesn't phone home. Yet despite that weak DRM, Sonar continues to be developed and sold.
Or in audio samples. The big name in virtual instruments is Native Instruments, their program Kontakt being the king of sampling. They have some fairly weaksauce DRM on their products. A challenge/response kind of thing that is cracked and pirated versions abound. Despite that, they make lots of money and are the unquestioned top of the sampling game. Then you look at EastWest who uses their own custom software with an iLok dongle because of evil pirates. They are too small for anyone to care about cracking. So no piracy, but they are tiny, a fraction of NI's size and profits.
Really all bitchy DRM does is increase the cost on the developer. You end up spending more programmer time implementing it, more QA time making sure it works, and more support time helping people when it doesn't. There's no good evidence showing it increases sales. Remember that decreasing piracy is not the same as increasing sales. You can drop piracy to zero and yet discover you get little to no extra sales because the people who were pirating were only doing so because it was free, and have no interest in paying for it.
