Not necessarily (and I'd be interested in the replies)? I mean, here's how I view it. If actors are part of the world, then they are part of its state. Hence, when the state of an actor changes, the state of the world changes. If we accept this, then there's nothing wrong with keeping the state of the 'world' and that of the actors in a single data structure (albeit a potentially massive one) and call this the new world (or universe). If you have the appropriate functions for finding an actor inside the universe and updating it, then you should be good to go.
