Metal Gear Rising: Revengeance - A video explaining the truth behind the game

How did Metal Gear Rising: Revengeance come to be? A video interview with Kojima Productions and Platinum Games staff reveals the entire story:

First announced as Metal Soild Gear Rising, Kojima Productions were finding it difficult to design the game around the cutting concept so they quietly cancelled in late 2010, and whilst Kojima had considered moving the project to developers abroad, he felt that a Japanese developer would be more suited to produce a ninja action game. So in early 2011, Kojima approached Tatsuya Minami, president & CEO of Platinum Games, about restarting the cancelled project with them. Platinum Games accepted the project and took over development and reworked the game from scratch using their own engine, whilst Kojima Productions handled the cutscenes and story elements.

Originally planned as a stealth action game set between the events of Metal Gear Solid 2: Sons of Liberty and Metal Gear Solid 4: Guns of the Patriots, the story was revised and will now take place after Metal Gear Solid 4 to reflect the new development style of being strictly an action game focusing on swordfighting.
