Back in March, someone asked the official SimCity Twitter account if an offline mode would ever be patched in to the game. The reply was negative.
“The game was designed for MP, we sim the entire region on the server so this is just not possible.”
Apparently, the wizards at EA have been hard at work opening portals to other dimensions and poloraizing flux capacitors because they have achieved the impossible dream! According to Patrick Buechner, general manager of Maxis Emeryville, offline play is coming. In the latest blog post, Buechner explained that offline mode will be coming as part of a free update to SimCity. In offline mode, save games will be stored locally, and all previously downloaded content will be available to players without he need to be connected to EA’s servers.
Update 10, including the offline option, has no launch date at this time, but EA promises to have more details in a follow-up blog post soon.
