Complete playthrough. This first DLC for The Case of the Golden Idol provides three new (prequel) chapters in very much the same style as the base game. Pleasingly, they're all quite challenging, but once again nothing's out of reach with a bit of thought and detective-work. The short length inevitably means that there's less of a wide-ranging web of complexity, but that can't detract from more of the wonderfully satisfying investigation and deduction formula.
