Bosh.
OF COURSE the dragons' actions are scripted. The dragons in the game are not real, living, breathing, thinking entities, nor are they managed by some sort of science fiction AI - they're computer generated representations, done under the limitations of modern technology. Their actions - the range of things they might do - might well be scripted with so much complexity that they appear, to the player, to be unpredictable, but they are. still. scripted.
It's misleading claims like this that discourage me most about this game. It's like watching a car commercial that says it gets 8000 miles to the gallon.
I bet your definition of "scripted" is entirely different from the definition used by the person talking about dragons. I don't know what that person's is, but his definition is probably correct and specific, and therefore his statement is probably not bosh. Your definition could very well be correct too, but you probably aren't talking about the same thing. No software engineer I know has ever named a compiled piece of programming a script, regardless of how linear or predictable it may be. They reserve the word "script" for other things.
