Cibele is an adventure video game in which the player navigates a simulated desktop computer interface to follow a budding online romance.

The story is based on the experiences of Nina Freeman, the game designer, and its simulated environment is that of her personal computer.

In Cibele, the player can rummage through Freeman's personal files, including emails, photos, and journals, and pursue quests in a mock massively multiplayer online role-playing game (MMORPG) to advance the story.

The mock multiplayer game, Valtameri, is designed to be incidental to the relationship that develops between Nina and Blake.

The story is based on her first love interest and sexual encounter, a relationship that developed through the massively multiplayer online role-playing game Final Fantasy XI.
