The new SimCity game will require an always-on internet connection when it launches next year.
Lead designer Stone Librande told Joystiq players will need to be online on Origin while playing due to the game's focus on multiplayer and regional impact, and its use of a global economy that all players can influence.
An EA representative also told the site that SimCity will be purchasable from digital distribution platforms other than Origin, although details of where it'll be available are still being ironed out.
Announced at GDC last month, the game is described as "a true rebirth of the franchise that brings the depth of simulation that has been the series hallmark for more than two decades and marries it with next generation accessibility and a robust multiplayer mode, giving players the power to change a world together."
The official blurb continues: "For the first time in SimCity franchise history, players' decisions will have long-lasting repercussions that will extend beyond their city limits.
"Together, players will address real global challenges such as climate change, the search for renewable resources and natural disasters. It's up to the players to decide whether to compete or collaborate to shape the world of tomorrow - for better or for worse."
