Which ending did you have on your first playthrough? Why did you choose those options? I sided with Iorveth. I found it hopeful that there finally was someone in the world with worthwhile ideals. Further down the road, I choose to save Triss, since Geralt had promised her they would go for a less eventful life together. (During the bathhouse scene.) Finally, I let Síleh die. I felt she deserved that. I spared Saskia, though, as she was a victim and too important for a stable North. I hope you can free her in Part III. In the end, I let Letho go, but only because he helped Yennefer and Geralt with The Wild Hunt.
