Yennefer, hands down. Seriously the most gorgeous, stunning & cunning female character to have recently graced the video game scene! (My other favorite female character is Elizabeth from Bioshock Infinite, before Yennefer came out). Never before I fell head over heels for a female video game character.
If only she could come to life (as good as she is in the game)
Triss in W3 looks a lot better than the previous ones but... sorry Triss. Don't get me wrong; Redheads are cool (you're not too shabby either) + you have bigger bewbs & sweet curvy @** than Yennefer but when Yennefer came out... she's just like a lady that came out of my dream.
Yen is love, Yen is life <3
