Simulations and games are highly integrated and iterative. Having every process be done in frames or steps makes the preservation of information for the next step/frame really important. Systems are also tightly coupled and not easily separated. That's why I like ECS. I also like the EC part to just be a table I can query, and the S system should be very tight and the dependencies should be used explicitly. That way you go around some thing like dynamic ordering of the update function based on object pools and other nonsense.
