Steam Apps Database listing points to possible expansion for Firaxis' PC strategy game titled "One World"; no other details given.
A new expansion for Firaxis' 2010 release Civilization V could be on its way, according to a listing on the Steam Apps Database.
The listing--first spotted on the 2K Games forums--clearly states "One World" as a PC expansion for the game, but provides no other details.
The last expansion for Civilization V was last year's Gods & Kings, which added new civilizations, scenarios, and leaders to the game as well as a reworked combat system.
