The City of Metronome is a cancelled adventure game that was in development for the Xbox 360 and Playstation 3 by Swedish developers Tarsier Studios. As we can read on Wikipedia, it was officially revealed during E3 2005 where it became an anticipated game for the seventh-generation of video game consoles. However, the status of this project is uncertain since Tarsier Studios was unable to find a publisher up to 2007.
On July 13, 2010, Tarsier Studios officially announced that the developer “has signed an exclusive first party deal with Sony Computer Entertainment Europe”, to work on Little Big Planet PS Vita. We still don’t know if The City of Metronome will ever be revived for the next generation of consoles or if it will be lost forever.
