I'm curious, since the scenery is 3D can we interact with it (burn bushes, etc...).

Nope, its there for ambience. While other games may support doing things like that we figured that if it had zero effect / meaning in the game world why bother. So you can crush a barrel or move a chair around how does that effect the game?

No barrels to destroy?  But that's where all the good loot is...
