Does it have some form of multiplayer? I actually grew quite fond of the Simcity multiplayer in the end although they could have done a lot more.
Sounds like me in Banished...
I don't think out-of-the-box, but there might be a suitable mod. I know there is already this mod:

With this new released version of the mod, players can join another player’s game from a workshop save and run around in the city. The mod doesn’t actually let you play the game together but it does show what is possible with the mod API and let you mess around with your friends.
