Just one more floor…. Perhaps the Bhurj Khalifa and and Shanghai Tower were not, after all, overblown acts of inter-continental willy-waving, but instead the result of builders and architects who could not resist the temptation of another neatly-wired layer of offices. Building skyscrapers is compulsive work, or at least that’s how building sim Project Highrise [official site] pitches it. I know the words ‘Sim Tower’ are flickering hungrily across the hind brains of readers Of A Certain Age, but I should say off the bat that Highrise has the mentality of an idle or clicker game as much as it does a sim.
