My biggest question is... why? Why now after all this time? In 2027, TW3 will be 12 years old. The complete edition with all DLC was released a decade ago. Can any game be considered complete now that they go on forever? Seems like they don't have much faith in The Witcher 4 if they're resorting to this.
Nothing about this shows they have no faith in TW4, that game is guaranteed to sell a crap ton of copies. I think this is meant to be a way to bridge the two games, so people get one last run with Geralt. I could see it being a story told by Ciri about Geralt or with it being "Songs", maybe it's an older Dandelion telling the tale.
It does make me want to give Witcher 3 another shot, I played it once when it first came out, but I found it abit rough and never really loved the gameplay, so after beating the game, I never went back, didn't play the DLC. I know they did updates and improvements, so I'm curious to see what I think of it now.
