While this term is used specifically for these types of games, there are several synonyms that can be used to refer to similar content in other languages. For example, hentai is a Japanese term used for sexually explicit anime/manga, while in English, the term porn games is used to refer to games that have adult content. Other synonyms for eroge include adult game, 18+ game, or NSFW game. Regardless of the term used, the underlying theme remains consistent - these are games that cater to adult audiences and contain mature content.
