Worst possible ending:
- evil tree spirit is released, Anna dies, the Baron hangs himself
- Cerys doesn't rule Skellige (can't make a choice which of the other 2 outcomes is the worst)
- mages get slaughtered in Novigrad (not helping Triss with evacuating them). Only a matter of time after that before none humans are next
- Radovid rules the north
- mages and none humans get slaughtered in the north as a result of Radovid's ruling
- Ciri dies
- Kira dies (no cure for the plague)
- Lambert dies
- Letho dies
- Emhyr dies (could result in a civil war)
- you end up alone

Anybody knows Corrine Tilly's (Novigrad dreaming quest) fate if you chase Sara away to Johnny?

nothing about Corrine - Sara joins Johnny
that's all

Then you have about as much empathy as Geralt did in such a scenario.
Are you serious? He was at the root of all of this; a kingslayer!

I'm not saying he's a good charachter, but I have a soft spot for this bad ass. He would never walked away from a fight. He was willing to risk his live against those bounty hunters in TW3.
Not to mention we didn't get to see many witcher from other schools.

We Don't know what happens to Ciri after (bad)ending - so we have 2 different situations for her:
-Death
-she is still alive but doesn't like returning (to geralt or anyone else(yen-avallac'h-emyhr)

@Fenixp: we still speaking about bad ending? our point: Ciri is Alive or Dead(after bad ending)!

Ciri can't die in your world. We get it.

Ciri will die
my main question (I must remind you!): during the worst ending!-geralt remains alive or he will die
and I got my answer: Geralt NEVER die !!!(mercy : heroes never die!)

There's a good reason why Geralt (or any such hero) can never die during the story: kill the main protagonist and you end your story -- Hollywood style character resurrections notwithstanding. If they die at the natural conclusion to the story, that's a different matter.

So the war is over?!

Huh? What war?

And resurrection of Geralt at the start of Witcher 1. Because... He sort of... Died at the end of the books. Anyway, I think CDP wanted to end Witcher games with Witcher 3 anyway. I guess they just want a backdoor in case they change their minds...

the witcher series was depended on the books (until now)
now it's free from the book and CDPR is free to tell a story and it's good
I hope they have plans for the (witcher's) future!
geralt is gone - it's a entirely new session for CDPR and the witcher fans
I'm sure they'll continue this ((masterpiece!))

I agree

but

the ends of the books he really died? The books can be room for speculation

I'm also sure that they continue (without Geralt of course)
Blood and WIne is a reflection of TW 1 with additional new content and retirement home for the hero of the TW 1/2/3 series

However CDPR reserves every door open from Storytelling ago

Well, to be fair even Sapkowski himself did this, in "Something ends, something begins" (the book). It's not canon to the main story, but it's still original author material. If the author can do it, I'm damn sure fantasy game writers have a huge precedent, and with Ciri and her time/space travel being the intervening medium, it makes perfect sense... sort of.
