Where can I find 'The Making Of' video?

Hey guys,

I purchased the collector's edition of Civ V back when it was released and I recall seeing a video where they go through the making of the game, from scratch, with focus on the technical side of things where they discuss creating the core engine first before creating the graphics and they actually show different versions of the engine in beta stages. I can't find that dvd so I looked online and I see several youtube videos of "Making of Civ V" but it doesn't have that footage at all, so I suspect it must be a different video alltogether. Does anyone know what I'm talking about and where I can find that video?

Thanks,

Anthony

Never mind... on a hunch, I looked it up for Civ IV and indeed it was a video for Civ IV that I saw, not V. Posting it here for those that are interested though it's old news :
