Worth noting that this is a very common method and used by high profile RTS's such as Starcraft 2. It does require your simulation be deterministic, of course, which can bring challenges depending on what you're simulating. Supreme Commander had challenges with determinism and physics if I recall correctly due to CPU bugs, although they eventually worked it out.
