I have played Witcher 1 in medium mode and the challenge level was pretty good. I decided to choose "HARD" for Witcher 2 :) maybe, as I do not mind retrying certain fights and for the challenge. I noticed, game is definitely very hard in this mode. I really am not sure how long will I keep Hard mode on!!!

However, I am in chapter 1 right now, regarding the fist fights and "Fight Club' quest... I noticed absolutely no challenge in any of them! For guys who are already ahead in this game, do these fights become more challenging?

let me lay it down.

hard only means that the normal fights get harder.

aah! So, it has no modification in the QTE or anything else?

well it does change how items are dropped and such. but the QTE do not change

Hmmm, thanks for letting me know :)
