No, it's more than that. You can have a box or something and be able to break it, but you can't shoot a grenade at a house and blow it up. For example, in Episode Two during final boss fight with all the striders, if they were to blow up a house, it was basically a cut scene. They pre-recorded the animation of the house exploding, and then put it in via scripts. So when a strider blew up a house, it was basically a scripted sequence.
