Worth the spend and the downloading!
The Combat system takes time to get used to, but i found playing Ch1 on easy the ramping up to difficult helped me get used to reacting to sound rather than visual queues.
The potion system I have found to be easy to learn and use, however the recipes are difficult to learn if you are just exploring and not sticking to the storyline.
Graphics are okay, but a bit more attention could have been paid to how hands move in real life (some cut scene have Geralts hands at crazy angles) also some time could have been taken to ensure hair and cloth interact with weapons and belts in a more relaistic manner( say hello the priests beard that can go into and out of hs chest..)
Overall a great game I have reccomended to several friends.
