EA announced today that it will be delaying the release of SimCity for Mac until August in order to "ensure a great experience" for players.
Today we are announcing that we are moving the release date of the Mac version of SimCity to August. We have made this tough decision because we do not believe it is ready for primetime yet. We want to ensure the Mac is a great experience for our players and that is why we are taking more time.
SimCity's PC launch was more than a little rocky, largely because the game can only be played online. EA requires that the game be connected to its servers at all times to facilitate region play where multiple cities are connected to share utilities and citizenry.
At launch, SimCity's servers were overwhelmed with traffic and the gameplay experience was extremely poor. Today, EA seems to have ironed out the bugs and users are playing the game as intended.
