The problem is there are different sorts of fanfics in the world.
Canoncial and uncanonical. When authors continue the original line and when authors make something really new.
Do you see something new and totally inappropriate to the books in the games (especially TW2 and TW3)?
CDPR tried to make a new Geralt in TW1 but then they decided to come back to the primary source.
In "Wild Hunt" instead of building the fresh characters and relationships we have tons of references to the books. At every step, almost in every quest.
Fanfiction or not but it's really hard to ignore the fact that this game is more than just "based on".
True, and I will try to clarify a few things.
I don't speak for CDPR ( obviously ) so this is just my opinion on what I have seen. that and i use fanfic because that seems to be a recurring term to describe the games.
I just see the game as separate, by that i mean it does not affect the books but is heavily affected by them, but at the same time has its own canon and story that is good. And while with the book you are along for the ride and watching things play out, the games give you the ability to influence and shape the course of the games. Those decisions not being canon in the games or books, so to argue against them is pointless.
the books are great, they tell a great story. The games allow you to take part in that great universe and shape it. so i just don't get the argument between them. they are two separate mediums that tell a story in a different way, and just because the games are not canon for the books, they shouldn't be dismissed. they are both relevant in their own way. I think that sums up my point.
Though I did play the games first, and CDPR is the reason I heard of the books. Not because they couldn't stand on their own, but i don't think any publishers were willing to risk translating them prior to the popularity of the game. So because i played them first and didn't look into reading the books til after TW2, my view might be a bit skewed. but it is my view.
I don't mean for this to be off topic though, my main reason for it was to just say that both books and games are relevant when making the choice in the game, and if a player chooses Triss ( even if geralt cannon wouldn't ) I don't see that as a bad thing. Same with geralt ending up alone or deciding to keep an awesome tattoo, because it is the players choice, even if it doesn't stick to the book canon. And if someone wants to play cannon geralt once he gets his memory back, more power to them, i have also.
I hope that clarifies it but not sure. And CDPR did good by the witcher universe i feel, so to dismiss it as simple fanfic does kinda annoy me. I just feel it demeans them and what they have done for the series, including bringing it to the world stage and not just eastern Europe.
Edit: Apparently it arrived in parts of Europe prior to the gives. Which I was unaware of that and wrong.

fftopic:
As for taking from the books more in TW3 than the other, I think they said they did that because they were introducing yenn, ciri and a few others from the books and kinda had to . though i may be mixing two different posts lol. that might be why they added the scene at the beginning with yenn, and why ciri and yenn do not have as much face time compared to ciri and geralt. In short, i don't have a answer to that :wondering:

I think i was trying to make that point as well, just not as well lol though I agree with your take on the books, I also feel that way when it comes to the games. When discussing them, I don't think you can favor the books, well you can, but if someone doesn't, that doesn't make them wrong either. And that is why i said i find the books vs. games tedious, they both play a role in the games. Ignoring the source material is silly but if someone chooses to, that is their choice. I address that next
And I was kinda addressing the small minority in the forums that do take issue to it. the forums would be aflame if majority of ppl did. so didn't mean to generalize.
as for fanfic, i agree it is, however i just have issue with the word. I think of one guy writing a story and posting it on a forum when i think fanfic. And CDPR did far more than that. that is just my view on it
