I’ve always loved Deus Ex. When it first came out twenty-five years ago, it completely changed how I thought about games. Until then I was playing straight shooters like Quake and Half-Life: run, aim, reload, repeat. Then Deus Ex arrived and asked me to slow down, read emails, manage an inventory, listen to conversations, and actually think. (A bit too much like real life, in a way.) It was my first real introduction to science fiction beyond cinema, and to the kind of near-future cyberpunk that felt possible rather than fantastical. It also made me realise that decisions in games could feel like decisions in life. Not the big ones necessarily, but the subtle ones: what to believe, who to trust, when to act, and when to listen. That sense of consequence lingered long after I closed the game.
Recently, I found myself revisiting it in a different way. I stumbled across Max Derrat’s video analysis, now about six years old, and ended up watching the whole thing. With everything happening in technology at the moment (the ethics of LLMs, surveillance capitalism, the strange new faith we place in algorithms), it all felt oddly familiar. The future Deus Ex imagined doesn’t seem speculative anymore. It feels like the world we’re already living in.
When Deus Ex released in 2000, it didn’t just give players freedom, it asked what they would do with it. Not just in the game, but beyond it. That was the revolution Warren Spector and his team pulled off: a game that didn’t lecture, didn’t hold your hand, but trusted you to think.
Before Deus Ex, most games handed you a role and a route. Heroes saved the world. Villains were obvious. The fun came from execution, not contemplation. But Deus Ex treated its players differently. It assumed we could question authority, notice contradictions, and weigh ethical choices with more than a points system. It was, in hindsight, a game designed to teach critical thinking through play.
Its story begins in a world already half-broken: corporate empires richer than nations, a collapsing democracy, and a global plague whose cure is locked away for the privileged. Playing as JC Denton (a cybernetically augmented agent for a UN task force), you start by fighting “terrorists.” But that label quickly unravels. Within an hour you’re overhearing conversations that make you doubt your mission, reading emails that hint at deeper conspiracies, and realising your employers might be the real villains.
That’s the magic of Deus Ex. The slow erosion of certainty. You learn to distrust your orders, your allies, even your upgrades. You begin to ask questions, not because the game demands it, but because it makes ignorance uncomfortable.
Philosophically, the game’s genius lies in how it merges design and message. It presents you with information (some true, some false) and leaves it to you to decide what to believe. It mirrors the real world long before social media blurred the same boundaries. In 2000, we didn’t yet have algorithms feeding us curated truths, but Deus Ex saw them coming. Its AI characters spoke of surveillance states and data control with unnerving precision, predicting the trade-offs between safety, convenience, and freedom that still define our era.
What really sets it apart is empathy through agency. Every mission can be solved in multiple ways: stealth, combat, diplomacy, manipulation. Each approach reveals something about who you are, or who you’re willing to be. The game doesn’t judge your choices directly. It just shows you their consequences. The true reward isn’t a new weapon or upgrade. It’s awareness.
Looking back, Deus Ex was a rare moment where game design and philosophy were one and the same. It asked: if knowledge is power, who decides what you know? And more importantly, what happens when you stop asking?
And maybe that’s why it endures. It wasn’t only predicting the future of technology. It was preparing us for it. For a world where truth could be manufactured, and belief could be programmed.
Next, I want to look at how Deus Ex took that idea further, when the machines we built stopped simply helping us and started thinking for us.
Special thanks to Max Derrat, whose thoughtful video essays on the Deus Ex series inspired many of these reflections.
