Adult-themed video games are designed for mature audiences and often include content that may be inappropriate for younger players. These games typically feature explicit language, sexual content, or graphic violence, and are usually rated by organizations like the Entertainment Software Rating Board (ESRB). Many adult-themed games explore complex narratives and character development, often pushing boundaries in storytelling. They can be found across various genres, including role-playing games, visual novels, and simulation games, appealing to players looking for more mature themes and experiences in their gaming.
