Here's a few ideas I cape up with, sort of effects and things to happen.
Falling Damage: When you fall and hit the ground, it would be cool if your character blew apart like a little blocko person. Like, upon impact, your player's head would go one way, your body goes another way, your hands and feet, etc.
Building Destruction: When you destroy a building from it's baseplate, it falls apart from bottom to top. It would be more realistic if it fell apart from the top down, like it collapsed.
These are just a few thoughts.
