I've been playing probably little over 10h so far and I'm liking it. I'm still in chapter 1 doing some sidequests.
I have to say that I'm not a huge fan of the new combat system. Maybe the added responsiveness in that 1.2 patch helps out, but as it is, it kind of feels like some retarded Ninja Gaiden clone where everything is worse. I'm not impressed by the graphics either. I'm playing at max settings except no uber sampling at 1080p. Maybe it's because I'm playing on a 100" projector screen, but imo there is nothing special about the graphics apart from some fancy effect here and there. The pop in is just horrible, shadows are bad and the general texture quality is nothing to write home about. The bloom/fog seems overdone and cuts the visibility. Imo the graphics and user interface already made it feel like a console port already before the announcement.
User interface sucks, maybe the new patch helps. I'm playing with a pad. Everytime I browse the menus or change equipment etc. it feels like I have to battle with the system. I think I need to use mouse for some of the scrolling and atleast I wasn't able to rest periods between the dawn, noon etc, without using the mouse, with controller it just moved the slider 6h at a time.
The world seems interesting and has a less western made feeling to it, which is nice. Having just finished Witcher 1 and now having the character be a total wimp without any reason is kind of a let down though, but what can you do? I don't know if disallowing "potion spamming" is a good thing. Now you just go to a battle, die, load and drink a potion before the battle, save and hope for the best.
I didn't have big issues with the infamous court yard battle though. Just drank a swallow potion and ran around a bit trying to isolate one or two enemies, used Aard sign to stun one or two and then attack someone. Took maybe 4-5 tries.
I'm liking it, but it's certainly not due to game mechanics or graphics.
