Wesker: I don't know if it was released outside of France, but there's also an adventure game set in the Forbidden City ("Chine : Intrigue dans la Cité interdite").
It had a 360-degree field of view, similar to Myst III, the graphics were rather nice for the time, the music was quite good, but it was quite (too) easy.
It came up with an in-game encyclopedia on ancient China and the life in the Forbidden City. Its content was probably quite accurate, since the game was co-edited by the national museums administration. Were you able to get an english copy of it, the existence of which I'm unaware, it might satisfy your curiosity on the subject.
Looks like it was released in english,
here is a review . I myself bought the french version some times ago in an Cryo adventure game pack, but I have not played it yet, can't say of it is good. If it is like like most defunct Cryo games, it will be a visually very nice looking game, with a quite interesting plot, but very linear.
