For a solo play or online multiplayer it's great but you won't be able to play couch coop anymore.
Big plus of the game is new city growth and building mechanics. Yo no longer expand borders autonomously but instead it's tied to city population. Each citizen claims new hex for your city. Aswell each new district expand the border and at later point you can add spec to districts. This system is far more relevant and have better view of what's in the city. Besides buildings from older eras can be overbuilt with newer buildings/versions of previous.
