One interesting feature of the game is the physics system of the game engine. In an interview, Molyneux expressed his dismay at the physics engines found in most RTS games:

"In most RTS games the player can get an archer with a wooden bow and arrows to fire at a brick wall and after like a minute, the wall will fall down."
....
"So the idea is why not introduce physics? You have walls made out of stone. How do you break stone down? You break it down with other stone, with catapults. You can't break it down with people with swords. It doesn't matter how long they stand there with a sword clunking at it, it's just not going to have an effect. And when that wall breaks down it doesn't suddenly disappear, you can form cracks in it: a little crack at the bottom, funnel your troops through, the other player can try to stop this gap up by building little boulders round the back. All of those things come from physics."

Despite the statements by Peter Molyneux, the impressive physics engine mentioned is not present during gameplay. Rocks can pass through walls without leaving a singe blemish, military cannot funnel through wall crevices and the creature is distorted to a large degree when navigating the land, especially when traveling towards enemy troops. Often a section of a building will be destroyed and the section above it will be left floating. Skyscrapers will tumble like stacked bricks, each level unrealistically detaching from the next. When attacking an enemy building, troops will run around the structure and (depending upon the amount of resources needed to build it) the walls of that building will just lower and lower until eventually the foundations are visible. Such an effect is not of the type that Peter Molyneux mentioned above. Contradictory to the above, segments of a structure that have broken off disappear almost instantaneously rendering them useless as far as strategy is concerned."

I like the physics in the game anyways, but can it be possible to make a mod to fix that? Make a mod where when the bottom of a building is destroyed the whole thing falls, and fragments of destroyed buildings stay around longer or until the building is repaired completely, and troops can go through cracks in walls, and even little rocks do atleast a little damage to buildings.

Can it be done?
