This weekend, something weird happened to me, and for the first time, I believe: I felt vertigo in a video game. There I was, running around the apocalyptic sandbox city of Harran in a zombie action game called Dying Light. A few hundred metres away was a radio tower – and as I’ve been conditioned over the last few years, towers are there to be climbed. There may be goodies at the top, or you get a better overview of the area and, more often than not, your map reveals points of interest that previously were invisible to you. So there I go, climbing the tower slowly and carefully, since no tower in video games has ever just had a single ladder taking you more or less safely from the bottom to the very top: it’s always a broken, rusty ladder here, some outside scaffolding there, and always at the risk of plummeting to your death and momentary rebirth at a safe place previously unlocked.
