I personally would love to see it in a Battlefield game, just think your running up a rubble ramp of a half destroyed building just to have a massive chunk blown up just in front of you, now normally you'd have to find a different route but with smart you can just keep going. Once DICE get the realistic destruction that want with the Frostbite engine the applications of SMART should be soo cool, or of course Brink2 anyone?
On the one hand, SMART and Destruction 2.0 are probably incompatible. It's difficult enough to make SMART work in a defined environment. But having it understand randomly generated terrain? That's a tough task!
On the other, SMART is build in the idTech 4 engine, I guess. Simply putting it into Frostbyte 2 probably doesn't work. There are engines like the Unreal engine which are basicly build to use 3rd-party components. But I think Frostbyte isn't like that.
