Developer Maxis is seriously considering an offline mode for SimCity.
Announced in the latest SimCity Blog post, Patrick Buechner, General Manager of the Maxis Emeryville studio says:
Exploration for Offline Mode is Happening
Right now we have a team specifically focused on exploring the possibility of an offline mode. I can’t make any promises on when we will have more information, but we know this is something that many of our players have been asking for. While the server connectivity issues are behind us, we would like to give our players the ability to play even if they choose not to connect. An offline mode would have the additional benefit of providing room to the modding community to experiment without interfering or breaking the multiplayer experience.
What are your thoughts about an offline mode for SimCity?
