Top gaming languages: where the players are and what they speak

Most of the world's players do not play in English, and the gap between that fact and the way localisation budgets are still written is one of the stranger habits of the games industry. Newzoo values the global market at 188.8 billion dollars for 2025, spread across 3.58 billion players, and 46 per cent of that revenue comes from Asia-Pacific. The clearest single signal arrived from Valve at GDC 2025, when the company's own account data showed Simplified Chinese overtaking English as the most used language on Steam across 2024. English has become one large gaming language among several, which means an English-only release is a regional launch that happens to think of itself as a global one.

For a studio or publisher weighing up new markets, the question is not whether to localise but where. The languages below are ordered roughly by commercial weight, each with current numbers attached.

A quick word about the other kind of language

Some people searching this topic want to know what languages games are written in, meaning C++, C# or Lua, and that is a reasonable question for a different article. This one concerns the languages players actually speak and read, and the distinction matters because a well-built game separates its code from its text precisely so that the second can change without touching the first. That separation, internationalisation, is what makes everything below commercially possible.

Chinese - Mandarin, Simplified

China is the largest games market in the world, and by Newzoo's 2025 forecast it is a genuinely close race with the United States: 49.8 billion dollars against 49.6 billion, the two countries together accounting for half of global spending on games. The shape of the Chinese market is distinctive, built on mobile, fragmented Android storefronts and social ecosystems such as WeChat that sit beneath everything else. Tencent's Honor of Kings illustrates the scale, finishing 2025 as the world's top grossing mobile game once again with around 1.7 billion dollars in player spending according to AppMagic, almost all of it earned at home.

The PC picture has shifted just as decisively. Valve's figures put Simplified Chinese at 33.7 per cent of Steam accounts across 2024, fractionally ahead of English at 33.5, a change powered in part by Black Myth: Wukong selling 25 million copies in its first six months. For localisation, the brief covers Simplified Chinese for the mainland and Traditional for Taiwan and Hong Kong, alongside a regulatory environment that reaches into content itself, from licence approvals to rules governing the depiction of blood and skeletons. Culturalisation here is simply the cost of entry.

Japanese

Japan is the third biggest market for games worldwide, worth a combined 28.5 billion dollars with South Korea in 2025 according to Niko Partners, and it remains the most self-sufficient of the major territories. Domestic titles dominate the charts, players show a settled preference for RPGs and narrative depth, and imported games with careless translations tend to be noticed, discussed and marked down in reviews with a thoroughness that should concentrate the mind.

Japanese readers infer quality from detail, which places unusual weight on register and characterisation: honorifics, levels of formality, and the difference between how a mercenary and a shrine maiden ought to speak are where a game either feels native or feels dubbed. Since Japanese text is often more compact than English, the engineering challenges lie in fonts, line breaks and interface conventions, all of which reward early attention.

Korean

South Korea, the fourth largest market in the world, is arguably the most committed one, a country where gamers make up over half the population, esports fills arenas, and PC bang culture keeps competitive play a social occasion. Niko Partners found that more than 40 per cent of hardcore Korean players react badly to poor localisation, with clumsy translation and inaccurate portrayals of Korean culture the specific complaints, so a weak Korean version does active damage in precisely the market where players are most vocal about it.

The commercial centre of gravity sits with MMORPGs and competitive titles, which brings a cadence problem as much as a translation one: patches, events and seasonal content all need localising at the speed they are produced, week after week, for as long as the game lives.

Brazilian Portuguese

Brazil anchors Latin America, a region Newzoo counts at 372 million players and 8.3 billion dollars in revenue for 2025, and Statista put the country itself at roughly 90 million players in 2024, most of them on mobile. On Steam, Brazilian Portuguese now stands at 4.42 per cent of users in the March 2026 survey, ahead of both German and French, a striking footprint for a language that many localisation budgets still treat as an afterthought.

Brazilian players reward publishers who address them properly, and addressing them properly means pt-BR rather than European Portuguese, since the vocabulary, slang and tone differ enough to make the two separate targets. It also means recognising that Brazilian gaming culture lives on Discord, YouTube and WhatsApp, so community content deserves the same care as the in-game text.

Spanish

Spanish is really two briefs sharing a name. Castilian Spanish serves Spain, a mature European market with deep console and PC roots, while Latin American Spanish serves some twenty countries led by Mexico, where mobile dominates and price sensitivity shapes monetisation. The Steam survey for March 2026 records Spanish from Spain at 4.81 per cent of users with Latin American Spanish counted separately below 1 per cent, though that second figure understates a region whose real activity happens in free-to-play mobile titles outside Steam.

The usual compromise for Latin America is a neutral international Spanish, and it works well provided the linguists writing it know which words pass unremarked in Madrid yet cause a snigger in Mexico City. There are more of those than a phrasebook would suggest.

German

Germany is Europe's largest games market, generating 9.4 billion euros in 2025 according to game, the industry association, a 4 per cent rise on the previous year in a country where roughly six in ten people play. With the average German gamer approaching 40, this is a mainstream entertainment audience with disposable income and correspondingly high expectations, which in practice means full localisation, voice included.

The language itself functions as a stress test for interfaces, since German text runs around 30 per cent longer than English and will expose every rigid button, menu and achievement popup in the build. The USK age rating system and Germany's strict rules on certain imagery add a compliance layer that regularly catches out the unprepared.

French

French opens France, Belgium and much of Switzerland, extends with care to Quebec, and increasingly reaches a francophone African audience as well. The care is the point: French Canadian differs from European French, and Quebec's language legislation makes proper fr-CA localisation a legal matter alongside a courtesy. France itself combines one of Europe's biggest player bases with a proud domestic industry, and because English proficiency is lower than in northern Europe, subtitled-only releases leave revenue on the table.

Russian

Russian holds third place among Steam languages at 9.21 per cent in the March 2026 survey, behind only English and Simplified Chinese, and its reach extends across Central Asia, the Caucasus and much of Eastern Europe. That breadth explains why the language retains commercial weight even while many Western publishers have paused direct sales in Russia itself. PC gaming is the historic heart of the Russian-speaking audience, with one of the most active modding and community scenes anywhere, though any strategy for the region now requires current legal and payments advice alongside the translation work.

Localisation is more than the script

Translating the text is the visible fraction of the job. Around it sit culturalisation, so that symbols, humour and history land as originally written; interface engineering for text expansion and character sets; localised voice casting; store pages and community content; and live ops, where the real test begins, because a game run as a service produces translatable material every week for years. Studios that plan for that rhythm from the start spend considerably less than those who discover it in week three.

Where Brightlines fits

Brightlines localises games and apps with native-speaker linguists who are also players, covering in-game text, interfaces, store listings, community content and ongoing live ops updates. If you are deciding which of these markets to enter first, we would be glad to talk it through.
