I think the game version of Emhyr really did want to leave the position as Emperor and the lack of an heir kind of made that impossible.
The Prophecy of ruling half the world then all of it would also make sense but if THAT were the case then WHY would we want to place her on the throne again unless we were closet Nilfgaardians?
I also got the impression that, as bad as Emhyr was, that he was utterly sincere in his desire to help Ciri and try to make up for their past.
The Empire was his "bribe" to get back in her good graces.
