Trees bend and sway, storms blow across the landscape, buzzards circle overhead. The Witcher 3’s world moves in a way that game worlds haven’t before. It’s one of the busiest ever made, and while it’s not the biggest in terms of raw square footage, it teems with life: human and otherwise. The Northern Kingdoms are both extraordinarily beautiful and sickening at the same time. For every cracked castle artfully placed on the horizon, there's a tree full of hanging men. You're constantly confronted by astonishing views, but something murderous always lurks in the bushes nearby.
