In the long, sad history of DRM (Digital Rights Management), also known as copy protection, there are countless examples that demonstrate its futility. The latest is courtesy of Bandai-Namco, producers of the console game 'Tales of Symphonia', originally released for Nintendo Gamecube in 2004.
The PC port of this old console game is a complete mess. But rather than spend some money to fix bugs, Bandai-Namco decided to waste money adding copy protection to the game. Because that's the default position of the corporate drones and lawyers who run most game companies these days. If they had stopped to consider this for a few microseconds, they would have realized that any potential profit they might lose to piracy is vastly outweighed by the bad reviews and angry customers with which they are now faced.
What's that definition of insanity? Doing the same thing over and over again, expecting a different outcome but never getting it? Bandai-Namco, you are insane.
