Ai Space (officially stylized as ai sp@ce) was a Japanese virtual 3D massively multiplayer online social game (MMOSG) developed by several companies that formed the Ai Space Production Committee which was launched on October 15, 2008 for Windows PCs.
A downloadable client program enables its users to interact through motional avatars with each other and primarily with bishōjo game heroines from three visual novels: Clannad by Key under Visual Art's, Shuffle! by Navel under Omegavision, and Da Capo II by Circus. After a player creates an avatar, one of the bishōjo game heroines is selected as a personal character doll, or "chara-doll", to live with on one of the game's three virtual "islands" which are patterned on the worlds featured in the three visual novels. The islands are connected by a central Akihabara Island where players with their chara-dolls can gather for chatting and events.
