When you play a video game, sometimes the words and dialogue are in a language you don't understand. This can be a problem if you want to fully enjoy the game and understand what's going on!
Fan translation is when a group of people who really enjoy a video game take it upon themselves to translate it into a language that more people can understand. They do this by taking the original game's text and dialogue and changing it into another language. For example, if a game was originally in Japanese, they might translate it into English.
These fan translators are usually not paid for their work, and they do it in their free time because they love the game and want to share it with other people. It can be a lot of work because they have to be really careful to make sure the translation is accurate and that it makes sense to people who speak the language they're translating it into.
Sometimes companies who make video games don't release them in certain countries, so fan translation is a way for people in those countries to still be able to play the game. Fan translate also allows people who can't read the original language of a game to experience it in a language they are familiar with.
Overall, fan translation is a really cool way that people who love video games can share that love with others who might not otherwise have been able to enjoy the game. It's a way of bringing people together through a shared interest in gaming!
