I don't like the ending.
I chose the Squirrel path. And in the end, everything ends up the same as it was before. Alvin/Grand Master dies. All the things I told to Alvin were mentioned by him, but it doesnt seem like the things I told him in any way affect the game.
I looked up on Youtube the other 2 endings, and they weren't much different. Either the order gains power, or the sorceresses.
There's no mention of Geralt post-game. In my game, I "realized that Triss was the love of my life." So what happens? She shows up for a few minutes as I make the final battle climb.
I really liked the game, but the ending and lack of variability due to actions kinda sucked.
