Learn a language by playing video games

A game you want to finish keeps you reading native text for hours — in context, tied to characters and situations, not isolated on a flashcard. Motivation is the hard part of language learning, and a game you'd play anyway solves it.

That steady stream of text you can mostly follow — comprehensible input, in language-teaching terms — is the main thing that builds a language. Which games suit this best is covered in game genres and screen-translation fit, and you can see how hard specific games are in our game difficulty breakdowns.

Learning from games outside the classroom has a research name, extramural language learning, and a body of studies behind it. In a series of studies following Swedish secondary students, the amount of time spent playing games in English predicted vocabulary test scores, and the effect was strongest for text-heavy genres such as role-playing and online games rather than for gaming in general (Sylvén & Sundqvist, ReCALL 2012; Sundqvist, Language Learning & Technology 2019). Work on learner communities around games describes the same pattern from the inside: players organize their own study around the games they want to play (Chik, Language Learning & Technology 2014).

The realistic reading is not "play games and you will learn the language". It is that games deliver a large amount of reading and listening you will actually keep doing, because you would play anyway. That volume is what builds a language; grammar and a dictionary still do their own jobs. Treat games as the input source that sits on top of them and the expectations line up with the evidence.

You rarely need to buy anything. Check these in order.

1. On Steam, right-click the game, open Properties, and set Language. For most games this switches both audio and subtitles.
2. If the game separates voice and subtitle languages, set both to the target language. Target-language audio with native-language subtitles trains your eyes to read the subtitles and ignore the audio.
3. If the language is not offered, check the store page's language table. "Interface only" still gives you menus, items and tooltips in the target language.
4. If the game exists only in the target language, with no localization at all, you are in the case where a screen translator earns its keep. Playing Japanese games in English walks through the options.

The moment you switch, the game becomes unreadable. That is normal, and it is where the rest of this page starts.

Playto's users look up and save words while they play, and grouping those words by CEFR level shows how game language is skewed. A1 holds basics such as game, time, find and right. C1 and C2 hold defeat, heal, hunt, combat, legendary and warrior: words a textbook files under advanced, and a game puts on screen in the first ten minutes. Japanese shows the same shape: the JLPT N1 list from real play is led by 俺, 所持 and 装備, the pronoun and the two inventory words every RPG uses constantly.

So a learner who starts from games builds a vocabulary in a different order from the classroom. That is not a flaw. It means starting from the words you meet most in the game you are playing. The level-by-level lists are published and updated from real play: English game vocabulary by CEFR level and Japanese game vocabulary by JLPT level.

People quit at the same spot every time: several unreadable lines in a row, looking things up gets tedious, and the language setting goes back. Three habits get past it.

First, stop trying to understand everything. Follow the thread of a conversation, and read item descriptions and quest objectives properly, because those decide what you do next. Second, cut the cost of a lookup to almost nothing. A phone dictionary beside the keyboard loses to tapping the word on screen by an order of magnitude in how many times you actually do it. Third, do not look at the meaning first. Read the original, then check only what stopped you, and the same word is yours the next time it appears.

Playto is built around those three habits. It reads the text on screen and shows the meaning in place, any word can be tapped for a dictionary entry and saved, and the Log can hide translations so you read the original first. The mechanics are in the in-game translation overlay.

Save five to ten words per session, not more. The failure mode of learning from games is not too few cards but two hundred half-interesting ones you never review. Save the word that stopped you, not every word you looked at.

Review the next day for five minutes and let spaced repetition schedule the rest: words you know stretch out, words you forgot come back. Splitting the work this way, meet the word in the game, make it stick the next day, is what keeps it sustainable.

As a rough guide, a few hours a week in a text-heavy game for two or three months is where a sequel or another game in the same genre starts to feel readable from the first screen. Changing genre brings a new wave of vocabulary, which is a reason to move on rather than a reason to stay.

Japanese has the most games that never leave their original language, and the most learners arriving this way, so it has its own step-by-step guide. English works in the other direction for the largest number of players: most games ship English, so the setting is one click away, and learning English by playing games covers that route. Chinese and Korean have large catalogs of untranslated games and the same reading problem as Japanese, and the same screen-reading approach applies. Spanish, French, German and the other European languages are mostly a matter of switching the setting on games you already own, and reading them with the habits above.

Japanese is where most people arrive from, and it suits the approach unusually well. The games are there, since JRPGs, visual novels and adventure games carry more text than most novels, and a lot of them never leave Japanese, so reading them is the only way to play them at all. The language helps too: menus and system text repeat the same few hundred words until they stick, and some games print furigana above every kanji, which removes the usual wall of not being able to look a word up because you can't read it.

If that's the case you're in, the step-by-step version is a separate guide: how to learn Japanese with video games covers picking a game, the read-keep-review loop, and what to do when it stops working. Our game breakdowns grade real screens by JLPT level, and the game Japanese quiz tells you where you stand in about two minutes. If you're curious what game vocabulary actually looks like level by level, we publish datasets built from real players' lookups: English by CEFR level and Japanese by JLPT level.

The same approach works for the other languages Playto reads. Japanese is simply the busiest door into it.

At first, that native text is just noise — most people stall on the title screen. Playto reads the text on screen and shows what it means, right there, so you can follow the game instead of guessing.

You read the original sentence — the real, native one — and lean on the meaning as a hint when you need it. The more you play, the less you need it. (More on the capture side in the in-game translation overlay.)

The meaning Playto shows is an AI translation, and AI isn't perfect — short lines and grammar nuance are the hard cases. That's why you learn from the original sentence, not the translation, and why it's worth checking anything that really matters. Playto is also exploring ways to ground word meanings in established dictionaries rather than AI alone, so the vocabulary you keep is anchored to a reliable source — not just a model's guess.

Playto handles immersion — getting you into native content and keeping you there. It doesn't replace grammar study or a proper dictionary. Paired with those, it's the part a textbook can't give you: hours of real, in-context reading from games you actually want to play.
