Great! But didn't have the RPG-feel that I expected. Gameplay became a bit linear but the story held it interesting.
The combat system was a bit lame, consisting of Geralt doing a chain of moves that you have to match with a mouse-click. I would call it passive. This was something I frowned upon at the beginning. However I quickly learned to deal with it, even though it somewhat ruined the gaming experience.
Also the RPG part was a let down when it comes to customizing Geralts attacks etc. I never felt that I could fight in an unique way comparing with other players. The shortage of armors and weapons bothered me quite much, I think there's only two types of armor and around 6 swords! On the other hand, the great thing about the role-playing is that the choices you make really makes a difference. If you decide to kill "wrong" person, you will have to face the consequences.
So without the great story this game wouldn't have been much. And if you want to maximize your Witcher 2 experience, then play this game!
