What Open Worlds Are Doing for EFL and World Peace

I want to be careful about how I frame this, because the subject requires it.

Open-world environments with open voice and text communication between strangers carry genuine risks for children. Unmoderated contact between children and adults they have never met is a serious safeguarding concern. The harm that occurs in these environments is real and documented, and any honest conversation about them has to start there. Children deserve better protection than most of these spaces currently provide.

With that said clearly, I want to talk about something that does not get discussed nearly enough.

These environments are producing some of the most effective language learning happening anywhere in the world right now. And almost nobody is writing about it.

The mechanics of it‍ ‍

The dominant language in online open-world spaces is English. It is the language of strategy calls, team coordination, quick decisions under pressure, and the slow social texture of spending time with people you have come to know over months and years. If you are a child from Denmark, Austria, Indonesia, or anywhere else where English is a second language, and you spend meaningful time in these environments, you are being immersed in English in a way that no classroom can fully replicate.

Immersion is one of the most effective routes into a new language. But traditional immersion requires travel, expense, and access that most families do not have. These environments offer something different: daily, voluntary, high-motivation immersion from home.

The key word there is “motivation”. These children want to be in these spaces. They have a reason to communicate. If your teammate needs to know where the enemy is, you find the words. If you want to be understood by the people you are playing with, you practise until you are. The feedback loop is immediate, and the stakes, within the game at least, feel real.

Research consistently shows that motivation is one of the strongest predictors of languageacquisition. These environments are generating that motivation in children who are spending hours a day inside them, without any adult having to engineer it.

Two people I know‍ ‍

I will not name them. But I know a fifteen-year-old from Denmark whose English is effectively indistinguishable from that of a native speaker. When I first played alongside him, I assumed he was American. He is not particularly academic. He has not had intensive tutoring. He has simply spent years playing online in English, absorbing the language through daily use, and it has settled into him the way a first language does.

I also know a young man from Austria who, yesterday, received 100% in his English examination. He is studious by nature, so this does not entirely surprise me. But I would put it to you that the examination result and the hours spent communicating in English with people from across the world are not unconnected. The language does not feel foreign to him. It feels like something he already lives in.

These are two examples from people I know directly. I could give you many more.

Something harder to measure‍ ‍

The second benefit is less tangible but possibly more significant.

These environments build friendships across borders. Real ones. I have friends from the Netherlands who visited me here in Scotland just this weekend, people I met years ago in an online space and have stayed in contact with ever since. Earlier this year, I visited them and saw something of the way they live, what they value, and how their society is organised. That experience changed how I think about things.

There is something quietly important about a world in which children from different countries spend time together, learn each other's communication styles, and develop bonds with people whose lives look different from their own. The research on contact theory suggests that sustained, positive contact between people from different groups reduces prejudice and builds understanding. These environments are generating that contact at scale, informally, and in ways that feel meaningful rather than engineered.

I cannot help thinking that a generation of young people who have genuine friendships across national borders is a net positive for humanity. The conversations about these spaces focus, understandably, on what can go wrong. What can go wrong is serious and must be taken seriously. However, these spaces are also building something. Quietly, at scale, in homes and through headsets, children are learning to communicate across difference.

That feels worth saying.
