One of the most often requested feature for SimCity, offline play, is now being deployed to the servers. EA's sent out word and have taken down the servers for this update to be rolled out currently.
The game will be unavailable for a few hours, but after that players should be able to take their city offline and play in the comfort of their own home without the need to connect to EA's servers. I'm going to guess there will be some minor hiccups, but all in all, a nice little step for the game.
Now, I just wish there was a way to increase the city size limit. It's rather tiny and you can cover most of the area in a relatively short amount of time. But, offline play is something that is welcomed so we will have that at least.
