Edge:Oh boy. We’ve no idea why it’s taken so long for someone to make a game that plays like a series of Quantum Leap, but D4, Hidetaka ‘Swery65’ Suehiro’s bonkers crime drama, is just that. Stepping into past memories one episode at a time, pretty-boy detective David Young hopes to track down the killer of his wife, Peggy, whose dying clue was to look for ‘D’ and alter history so that she can come back to him. So far, so grim. But the director of Deadly Premonition was hardly likely to serve up a game without humour and oddball characterisation, and it is in embracing both that D4 – which stands for Dark Dreams Don’t Die – veers sharply off the conventional track.
