How so? I've been here the whole time. It is difficult because of Geralt's relationship with Yennefer and also because of Geralt's relationship with Triss, in the books. Nobody cries canon as you say. It's just that the Triss option would need a lot of support to actually make sense. In my opinion, as I've explained in previous posts, in the games, the Triss and Geralt relationship does not quite match the Geralt/Yennefer. Not even close. And since the writers try to stay true to the books, they will have a difficult time bringing Triss to a similar level as Yennefer. It is just my opinion though. And as you say meaningless.
Again nobody is talking about canon. Canon is defined by Sapkowski. We are talking about choices actually making sense, assuming that the writers stay true to Sapkowski's characters.
