Mean Girls

In 2004, Tina Fey's film Mean Girls, starring Lindsay Lohan, became an unexpected box office success. Five years after the film's premiere, a video game based on it was created for the Nintendo DS, turning the movie into a sort of cult classic.

For a while, it was believed that the game had never even been launched; Lohan wasn't even on the cover, apparently due to her reputation at the time. However, that didn't stop someone from discovering it. One of the Mean Girls developers noticed Raven, who had built a career out of describing lost and forgotten DS titles, and shared a copy with her after several years of searching, looking, and appealing.

A playable version of the game was eventually released once it had been emulated and debugged. Although no one has claimed to own a physical copy of the DS version, it may have been sold in Europe on a very limited scale. If so, it's probable that there aren't even any authentic copies of this left.
