The Witcher - Toolset Interview @ TW Vault

The Witcher Vault has a short interview with a handful of CD Projekt Red developers on the Djinni toolset.  Unfortunately, I'm still not clear on the scope of the toolset but have a read, anyway:

What was behind the decision to release a Mod toolkit for The Witcher?

The Witcher was always a game with a lot of potential. We have always tried to do as much as possible with it and we feel that releasing the D'jinni toolkit to the community is a natural step for us to take. It's the only way to really let the game grow beyond anything we could do and imagine. There are many talented people in the community and it will be interesting to see what they can come up with. Personally, I'm very eager to see the results. :) - Daniel Sadowski, engine programmer
