One of the best real rpg for pc.
The story is great and full of twist and choices, there are so many choices and they impact that much in the game that in one part the game will completely take another course if you choose one thing or another, so it feels like a real old rpg where your actions means something, and is non linear at all.
The voice acting is just great and is full of good dialogs not for kids be aware, the game is full of sex, drugs and other things but not in a bad way and they are in the game for a reason not just for the meaning of say "yes the witcher 2 have sex scenes or they talk about drugs" for example in one part you talk to some soldiers and they told you that the only way they could tolerate what war have done to them and forget all of the pain is was by using drugs (I'm not saying that using drugs is ok or is the way to fix the problems i hope you get my point here) is just like a movie with very mature themes and dialogs, even the jokes, so again this is not for kids!!!!
About the graphics they are amazing one of the best graphics out there and even with a low pc you can run the game pretty decent, is more than well optimized and the developers are always launching patches for fixing bugs and adding more stuff, yes they actually care about the players and customers and they hear what they want(adding the possibility to store items, a tutorial an arena etc etc) without turning the game into some commercial way(Ejem mass effect 3 co-op mode ejem.)
Oh and every DLC they release is free and comes with the patches :) yes they are FREE!
.
The game is hard at the beginning very and it has a very hard learning curve, it took me hours to fully manage everything on the game, from the alchemy and potions, to the combat system but once you get it is very rewarding and satisfying!
So don't quit if you get frustrate at first just give it some time.
Other important stuff is that the game doesn't have DRM yes no protection at all so support this game and buy it, show the industry game that they don't need to do things like ubisoft with their games(play connected to the Internet for example...)
I'm playing the 2.0 version and did not find any major bug.
One last thing, stop reading reviews and go play it!
