Hereā€™s a recap video from this yearā€™s GDC, via Gamasutra, that details how CD Projekt Red built Beauclair, the beautiful fairy tale city from The Witcher 3: Blood & Wine.

It gets fairly technical in points, but I think anyone who played the game and marvels at how CDPR are able to fit it all in can appreciate the work that went into it.
