GB Feature: The Witcher Q&A, Part Two

The second installment to our The Witcher Q&A is now available, in which the CD Projekt team addresses questions about magic items, weapon types, multiple endings, and more. Here's a little something to get you started:
GB: What effect will the day and night cycles have on the game? For example, will fatigue set in after a certain time or will it become more dangerous to travel during the night?

CD Projekt: The day and night cycles will influence the gameplay greatly. First of all, some of the quests will only be achievable at night, e.g. slaying the monster, who appears only after the darkness has spread over the lands. Such quests will be numerous. Nights will generally be the time of dangers, even in the cities, where all kinds of scum, be it burglars or even murderers, wander the streets after the sunset. When tipsy, the player should also watch his back, for the city guards patrol the streets, canning every suspicious individual. Obviously, outside the city walls one can expect various beasts to appear. The NPC's will as well act accordingly with the day and night cycles, following their daily routines during the day, and resting after dusk.
