Good
A great game that has been covered in some detail. From the start there is great atmosphere that is hampered in some way by the age of the game. Having just played this game in 2011 I am pretty impressed with what was accomplished by this old engine.
While the combat is interesting and the game systems help to add some diversity the main issue with The Witcher is the large amount of backtracking. There are large sections of the game that are retreading the same area over and over again with fighting some of the same monsters which are essentially defeated with well timed clicks.
Still, you owe it to yourself to play this game. The story is good, the choices are those that are not all good and all bad. I am very excited to play The Witcher 2.
