I’m a simple man, driven by simple pleasures. Such as when playing a climbing simulator, deliberately placing one foot on the rock, and then with arms by my side, placing a second foot on the rock. And watching the character fall stupidly on his back. But then I’m a twit. Vertigo is actually a rather serious climbing game, very impressively recreating the necessary actions and thought that goes into scaling a vertical surface. Using ragdoll physics, you control each of the guy’s four limbs to find grips on a rockface, seeing how high you can get him. Which is more interesting than it sounds.
