Aryan Lives -> Iorveth Path -> Stennis dead -> Save Triss -> Spare Letho.
What can I say, I'm a sucker for redheads.
I did a complete playthrough a half year ago:
Chose Triss in Witcher 1-> Neutral-> Saved Adda- >Didn't give the grandmaster's corpse to the King of the Wild Hunt (though I doubt it matters)
Killed Aryan-> Iorveth Path-> Stennis alive->Saved Triss> Spared Cynthia/Sile/Saskia/Letho
Though I'm not 100% happy with this save. I regret killing Aryan. Mainly because his mother had to make a deal with Nilfgaard in this case and i don't wan't to support them in any way.
I started a speedrun (skipping all dialogues) a few days ago to correct that decision but I played this game so many times, that I can't motivate myself for another playthrough. Currently stuck in the middle of act 1 and I doubt I will finish it. So I guess I have to live with my decision:(
Though I doubt our choices will matter that much. Temeria seems to be conquered anyway so maybe it won't really matter if the La Valette lands are Temerian or Nilfgaardian at the end of Witcher 2.
I just hope I will get a reaction from Yennefer on my Blue Stripes tatoo and all the whoring around in the first 2 games.
Checking the wiki my Geralt slept with 32 different women during both previous games in his canon playthrough.
I think that deserves an angry Yen if she knows:)
