UPDATE 19/1/15 4.45pm: Sid Meier has spoken to Eurogamer.de about his new project and revealed a number of new gameplay details - namely that you'll be playing as the admiral of a federation of planets.
Familiar faces from Civilization: Beyond Earth will also appear.
"The key elements are designing and building your own starships," Meier explained. "Develop different kinds of weapons, stealth abilities, armour and shields. Put all the different pieces of a ship together in different ways, to get different kinds of ships. Some will be fast, others will be powerful, some are used for stealth, and your role will to be the admiral of this fleet.
