Despite connection problems plaguing

Despite connection problems plaguing the opening days after launch, city-building simulation SimCity has sold more than 1.1 million copies, publisher Electronic Arts announced.

More than half of those copies purchased were digital downloads, EA says in a statement.

"SimCity is one of the storied brands in gaming, and Maxis delivered a game re-envisioned and engineered for the online age," says EA chief operating officer Peter Moore in a statement.

Launched two weeks ago, SimCity had suffered through a myriad of technical issues, most notably an inability to log on and start building cities. The game requires players to maintain an online connection throughout, even when exploring single-player components.
