Sacred 2 - Quests @ IGN Blog
Ascaron has updated their IGN blog with an example of how their in-house quest editor for Sacred 2 works:
At Studio II we use our custom-made quest editor for implementing stories and quests in Sacred 2. In any game a quest basically consists of the following components: characters, items and interdependencies. You could very well program them using a scripting language, but it's a lot easier to just select all elements with your mouse. You still may use the scripting language for all the other stuff, but usually that's no longer necessary.
