If you, like many people in this crazy world that we call video games playing, prefer to play alone before reaching into the sick, sick world of online gameplay then the news form EA and Maxis will make you smile out loud.Well, we can't promise that offline SimCity (rebooted and reimagined) will come along soon, we can however, tell you what Maxis says about it: 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. "
