The W2 Geralt looks a bit like a hybrid of W3 and W1 witcher. It's like Geralt evolved into the W2 witcher, then made the progression to the W3 one. In the process his face grew longer lol.
In my mind Geralt and Yenn are the witcher 3 game versions, and no one else. same voice too. Same thing with adult Ciri. However child and young adult Ciri is a bit different. I don't really acknowledge Netflix versions lol.
With Triss, I think of Triss as being the W3 version and also the one in the books. the one in the show is fine, except for the way she looks.
