Soren Johnson is one of the leading names in strategy game design, so it’s welcome news that he has a new project in the works.

Johnson is best known for his work on Civilization 3 and Civilization 4 for Firaxis as well as the innovative Offworld Trading Company, developed by his own company Mohawk Games.

His new game has a working title of 10 Crowns. Publisher Starbreeze today announced it has picked the game up. In a blog post, the company said that 10 Crowns is “an epic-scale turn-based strategy game that lets players create the greatest dynasty in world history.”

In a statement, Johnson said he and his team are “going back to our game development roots to make a classic historical 4X strategy game with some important and radical innovations to the genre.” Dorian Newcomb, art director on Civilization 5, is also working on the game, which is still at the prototype stage. Concept art was released today (see gallery below).

In the meantime, if you’re playing Civilization 6, keep an eye out for our review of the new expansion Rise and Fall, which we’ll run later this week.
