I was telling a friend of mine today about GalCiv2, and how it was 10 bucks cheaper than other new games. I also told him there is no piracy protection, just a serial key for updates. Lastly, I told him the game came out very buggy with CTD's which would be fixed later. He then told me that the serial key for updates IS the piracy protection. simply because if you copy the game, and dont have the serial code you wont be able to get rid of the many bugs. aka the game wont be enjoyable. whereas the legal dudes have the code, update and their game runs smooth.
I doubt the bugs were planned against piracy, but it's an interesting concept. Buy legally or your game will crash. Oh, and the bugs were left in there by *cough* accident *cough*.
like I said, I doubt GalCiv2 was protected in this manner on purpose, but damn its a good idea
