I bought C&C Generals when it first came out. After a few years, I felt like playing it again so I dug up the disks only to find they were scratched up (it was useable for the cd check, but not to install). Some time prior, I did a complete backup of my HDD with a cloning program. So I grabbed the game off the old drive and put it on the new one. But since I was now using a different operating system, the game wouldn't run anymore. So I fudged the registry entries, and booted up the game. It loaded fine, chose the side I wanted to play, and settled in for an afternoon of blowing stuff up. But, the game's anti-piracy feature kicked in. The moment I clicked on one of my units, everything (buildings, tanks, troops) all blew up.
