I know I'm going to catch flak from this, but I think MS should make the trees and buildings (autogen and fixed) destructable. If your plane hits a building, the building should set on fire and eventually either explode or collapse, using model switching or something of that nature. And, this should be able to be seen over multi-player. Think about it, a plane crashed on VATSIM. The virtual Coast Guard or Virtual CAP goes in, see's a smoke trail in the distance, and finds a huge crater in the woods. The crashe even started a forset fire, and the virtual water bombers squadron comes in and dumps water, putting out the flames. These kind of things would add adventure/mission type scenerios, without the need to go to a linear level-based type of game. I think this would be a great addition, especially with the more interactive worlds we now have (Cars, deer, etc). This doesn't seem too har to do, I'm no expert, but maybe a couple of damage models for the autogen buildings, some fire and smoke effects, and some kind of xml program to allow fires to spread and be put out by water bombers. What do you guys think?
