Well, I kind of imagine that in the transitional zone, where Chaos reigns but does not reign utterly supreme and occasionally has to grudgingly nod the head vaguely in the general direction of reality, there's a band where it kind of does work pretty much like those old 'god games' such as Black & White and Populous. That is, reality is malleable and how much people can accomplish has a lot to do with how much attention their god is paying, but the god's attention is still in some sense a finite 'currency' that has to be spent. So the big floaty divine hand can accelerate a building by sprinkling bones from the bone pile on it, but it can only be in one place at a time, or whatever.
This is mostly just me being light-hearted and bantering, and playing around to be clear, though I'm not joking or knowingly misrepresenting things. No need to waste your time replying if you don't feel like it.
