SpaceSector has part 1 of their Community Interview up which took several questions from the community and were answered by our own Ray Barton, producer on Galactic Civilizations 3.
"Kordanor, adarax: Regarding multiplayer, will there be simultaneous turns or IGOUGO turns? If there are simultaneous turns, will the orders be executed right within the turn or will they be executed “between” turns? Will there be a special lobby for multiplayer? Meaning, will Steam be required or another platform for that purpose? And, will there be LAN multiplayer?
Ray: Galactic Civilizations III has simultaneous planning (ship design, planetary projects, ship path planning, research and tech tree choices, etc.) and sequential execution (battle, discovering anomalies, colonizing planets, etc.). Currently right now there are no plans for a separate LAN multiplayer; all multiplayer will go through Steam."
