Moore also stated, about Century,: "I suppose that if there’s an overall moral to this third volume, it's 'Times change.' Invariably, throughout human history, that has been the lesson: 'Times change.'
And I think right now we’re going through a period of change, quite violent and rapidly, at least in my summation of the moment. And hopefully, the speeded-up view of the twentieth-century-to-present in this volume will feel quite appropriate."
So that seems to be his explanation for why they are doing it this way. Times change? Screw that. I want my Hyde back! And AJ Raffles!
