I think there is no game in rpg genre that manage to make such great relationship between father and daughter. Ciri is simply the most important person in the game, both for Geralt and us, the players. As a book fan im super pleased with having so much dialogue and interaction between Ciri and Geralt. I love every single cutscene with her, specialy the reunion was done really well. CD Project Red, you made my proud. Yes, there are some things that are not so great. There is to little interaction between Yennefer and Ciri, not to mention Triss. Even with this small complain, im amazed how good CDPR made Ciri. She had some really hard times in the books, thats why im glad that finally her story ends well (both witcher and empress ending are for me good).
This is one of the rare cases that i, the player, actually cared really much about a video game character. Yes, it sounds strange, you can make fun of me if you want. I wanted Ciri to succeed in winning against the Wild Hunt. I wanted her story to end well. Maybe its the influence because of the books. I only know one thing, i enjoyed the entire content of Ciri in the game.
Just my 2 cents on the topic.
