At its core the problem game programmers run into is that game state is very globalized with a lot of dependency overlap. You can push around the data into different containers and declare dogmatic methods of access, but you always wind up with the same problems: The animation state depends on the physics. The rendering depends on the animation state. The physics of a local entity depend on its collision with the rest of the world. The results of physics depend on which things collided first. And so on and so forth.

And so games live within this environment of confusion over which things happen when. At every point there are a few defensive tools - queue up actions in a buffer, poll values instead of copying them, etc. - but the overall management of these concurrent, overlapping systems remains a challenging task lacking in silver bullets.
