Well, there was only one choice which decided what kind of Chapter 2 you were going to get, and I was rather annoyed when I got to Foltest's camp that a lot of content was blocked. I would have liked to have known that I was making that choice when I gave the sqoyatel (sp) leader his sword. It didn't feel like I was shaping the story, more like being forced down a binary choice same as Witcher 1. Maybe it was the fact that they spent too much time evening things out so there were no wrong choices and no right ones either. Sure the humans persecuted the non humans, but the elves were just as murderous and, who knows, probably had done the same if they had been in the majority. So we are just left with two racist camps one of which is going to hate you, the other call you their champion. The end result was that it got hard to care about any 'cause' and this made the forced choice between them a nuisance.
Consider just how much work is going to have to be put into TW3 just to fit in all the paths in TW1 and TW2 and have them be slightly significant
I wouldn't worry about that, Geralt has recurring amnesia.
