Aside from the amount of fan-in, another difference that seems important to me is that a “normal” simulation is guaranteed to have exactly one continuation. If you do the thing where you simulate a bunch of possible futures and then prune the contradictory ones then there’s no intrinsic reason you couldn’t end up with multiple self-consistent futures—or with zero!
