Russian fansite KaerMorhen.ru has posted an English version of a recent interview they conducted with The Witcher 2 senior producer Tomasz Gop. Since the questions were all fan-submitted, there are quite a few good and slightly unconventional answers to be found within. Here's an interesting series, for example:
How would you describe the combat system? Will it be easier than in TW1? More casual?
I think it's too general to say whether it will be easier or not. Because now we have combat system that is more advanced. I mean it took more time to design this system. Some features were taken from The Witcher: Rise of the White Wolf. Some of them we took from previous projects. But it was only a small part, most features were created specifically for TW2. There was a lot of work and a lot of features. We have worked for few years, only on combat system alone. But on the other hand we want to be sure that on the easiest difficulty level the combat will be really easy, easy to learn. But if you are a hardcore player and if you want to learn all these advanced features, you have to play more then you did in The Witcher 1. So it's hard to become a master in combat.
Will it be possible to get drunk and go on a rampage, leaving only dead bodies behind?
I don't think it's a good idea to try to kill everybody when you're drunk. It might be too difficult. But actually, you will be able to kill more NPC's than in TW1. But still, you have to remember that there are unique characters that influence the story and you can't kill them.
What level cap do you plan?
Well I know we have a level cap but I don't know what number it is.
Will monsters spawn in location only once or from time to time to make leveling easier?
Depending on a quest. You probably know that I mentioned earlier that there will be something like an ecosystem. If you are just killing monsters in a location and don't want to know how they behave and where they live, they will re-appear from time to time. But whenever you want to go on an adventure of finding out what they are, you will be able to find the nest of these monsters and after killing them all they will disappear forever.
