In the game 7 days to die it is works almost good. The players buliding only solid blocks (wood, iron, bricks...) that is not affected. It is difficult to build with dirt, snow. (like not possible to build a dirt shelter) and the blocks has stablity (Structural Integrity), weight and affected by gravity. It is a complex system, sometimes slow and heavy on cpu/ram but it works. (not 100 percent)
