The ending choice of the Yennefer romance is underrated. You get to decide the meaning of their long, tumultuous story. Both the heart break and the happily ever after are cathartic, satisfying conclusions.
Though maybe you need to read the books for the full weight of it to land, especially for the heart break option.
I really need to replay Dragonfall and Hong Kong. Never finished either just due to unfortunate circumstance outside the game but thought highly of both.
