The cloud in C3 is not use to bring something new but to scale it up multiple time and add more realism to it.
You could argue that this is possible with dedicated server and you'll be right thechnically but not finnancialy.
Cost to have enough server to do that would be insane and seriously affect the game rentability and will automatically lead to server being close prematurely.
On a cloud platform like azure ressource are affected dynamically based on needs. It can scale up when more player are online and scale down when not, unlike dedicated server, this remove the needs to ever close the server. but even with this it would be hard for dev to add feature like this to a game because cloud computing is costitive and on that scale at his peak it would cost many M$/year.
With the cloud on Xbox platform fees are not assume by publisher but by gamers Xbox live subscription so the cost to add a feature like this to a game is the cost they have to assume when creating it that's where the true power of the cloud is.
