Ciri is not fit to be the lead of a Witcher game, but instead she is more fit to be the protagonist of a Japanese RPG.
She has a weak and one dimensional character. A beautiful princess who has been granted a powerful gift or curse, and everyone wants a piece of her. She is a Marry Sue and a cliche in every aspect. She can jump through space and time, and turns into a light beam on the battlefield instead of blocking and dodging. She has the Elder Blood and all the other high fantasy going for her. The way she looks and sounds are also JRPG material. She is not fit for a dark grounded medieval fantasy.
This is my opinion after reading the books and playing the games.
