Densen was a game that was announced for the Playstation 2 by Sony Computer Entertainment and was quietly cancelled later.

Despite the game already looking great, it never saw release, and yet it still managed to influence many people. The most notable of the people this game inspired are the likes of Keita Takahashi (creator of Katamari Damacy), and even Fumito Ueda, the creator of Ico and Shadow of the Colossus.

Densen saw the female protagonist zipping along the power lines in fantastical, floating Japanese suburbs. It also featured various power ups, and even traditional platforming elements as you had to navigate between areas by jumping between different power lines. Maybe this is where Irrational Games got the inspiration for the skyhooks in Bioshock Infinite?

All jokes aside, the game was being developed internally by Sony Computer Entertainment Inc., and it was helmed by Kiyoshi Sakai, an animator who worked with  Hayao Miyazaki and Isao Takahata before they formed Studio Ghibli. Sakai later became famous for the Umihara Kawase series, which is still seeing new media, the latest being the release of Yumi’s Odd Odyssey on the Nintendo 3DS.

The video came from the October 1999 issue of the Playstation 2 magazine プレプレPLUS.
