For me, and likely many others, the most exciting thing about The Witcher 3: The Wild Hunt is the open world map. And now, thanks to Playstation Access, we can watch Geralt travel from one end to the other, following the roads and giving us an idea of the way everything is positioned and an overall feel of the environments.
It's really an interesting video, and a great appetizer for the game's release next week on May 19th, without giving too much away. And good lord is this game beautiful; I still marvel at the trees bending in the wind every time I see it.
