I love Platinum Games. I played Bayonetta and God of War III back-to-back and thought Bayonetta absolutely destroyed its far more hyped competitor. I also love the way the team is dedicated to quality above all else. If you feel the way I do about Platinum Games, and even if you don't, this short behind the scenes documentary about the inner workings of the studio is absolutely a must watch.
There's some pretty fascinating footage of the studio's latest project, Metal Gear Rising: Revengeance, in addition to some pretty insightful interviews about the design philosophy of the team. Interesting stuff.
A quick bit of advice -- to get subtitles, click the 'cc' button on the bottom right hand side of the video.
