Brave New World is the second expansion for 2010's Civilization V, following last summer's Gods & Kings add-on. The expansion is geared around tweaking the game's culture and diplomacy mechanics and also offers nine new Civilizations, eight new Wonders, and two new scenarios.

Brave New World also introduces the World Congress and the concept of international trade routes. The World Congress will convene on issues like trade sanctions, hosting the World Games, and the use of nuclear weapons.
