A computer game company developed a role playing game where the role is to be a games developer. Players design and market games and make pretend money by selling them.
On the day the game was launched, the company posed as a hacker and posted a hacked version of the game on a file-sharing site so people could download it without paying.
But that second version was different. It was built in that, when a player started to earn money by selling games, a 'pirate' would start to syphon off the money. The inevitable end of every game was that the player ended up with no money.
The irony is that various message boards etc. have had postings from people playing the stolen game complaining about the theft of their income.
The game developer can take some quiet satisfaction from messing with the thieves but is it likely to make anybody think twice in the future?
