Even if it's is in the NDA
A lot of your answers are probably here:
play.net >> Where adventure finds you.
Actually, it's funny but, that site kind of shows you a WEALTH of information about HJ itself. Just look how complex interactive item placement works. Look how pathfinding works. And finally, look at how multiple zone designing / world buliding works.
Basically, you can see most of the tools to build the game are simplistic. You can see HOW they are building it, and you see a LOT of video here on the animation in the game and what the graphics look like.
It's actually way more info I've ever seen released about a game before the game ACTUALLY approached beta.
