GDC2012: Slides for Good, Bad, Great Design

Here's the PDF: Koster_Raph_GDC2012.pdf

Here's the PPTX, which includes the speaker notes, which this time are extensive: Koster_Raph_GDC2012.pptx

And the closest I can get to the speech itself is this page here, which has an image of each slide, followed by the notes… so you can just read it like an article.

I imagine video will be up on the GDCVault eventually…
