As a proof of concept, Reigns: Three Kingdoms is intriguing. As far as allowing players to travel through history (and/or literature) and play out “what if” hypothetical scenarios based on moral decisions, there is clearly a lot of potential here. Is there a future where we can talk sense into Napoleon before he marches on Moscow, or give Romeo & Juliet a happy ending? Reigns could well give that to us. For it to truly work, though, the developers just need to manage continuity and introduce a sense of consequence to our actions when trying to reverse history. That way, when we successfully do achieve something, we can feel like actual heroes in the story.
