Ok now ive see it all i gona summarise 3 points of what i think about the endings.
- If Geralt kills Dettlaff, at least Damien must ask him how he was able to do so, since Geralt himselft told him and Henrietta that only a vampire could do that, what Geralt will askwer to that? probably with some evasive, something like "there is another vampire but i cant tell you who it is", if it left as it is, that just a huge plot hole.
-On the tragic ending since the sisters are on the same tomb, i remember the quest "Till death do you part", so i returned to their graves hoping to see some kind of hidden scene, where the sisters make peace with each other, maybe using part of the dialoge of the happy ending here, a shame, that could be good to make up for the people going to the unseen and being forcely locked up intro this ending.
-On the 3rd ending Geralt letting Dettlaff live makes no sence, at this point not even Regis wants to let him go, if Geralt let him go, is letting go the guy who attacked the city and killed hundred of innocents, killed Henrietta sister, and blackmail or not, is still a very impulsive murderer who does not understand humans and acts like a child with a gun... not only that, but Geralt is now an accomplice of the "beast of Toussaint", NO WAY, not even Geralt wants to let him go, he says cleary "we are letting a murderer go". Also there is no way that Dandelion could get him out of that one, nor he could keep the Vineyard either, the entire population hates him, they will probably burn it to the ground.
Im sorry, but letting Dettlaff go must be the equivalent of "Ciri is missing" on the main plot here, maybe with Regis rescuing him from the prison and them tell Geralt to get out of Toussaint and never go back, no matter what Syanna did, there is not excuse for what Dettlaff did. And Regis did not wanted Syanna dead either. With Dettlaff dead this ending is just fine.
And seriusly, it will be nice if final slides could be added to see the future of Toussaint and the characters.
