One of the first big changes noticeable in BNW at the very beginning of the game is the addition of a new trade route system. There are more distinct visual tweaks and performance improvements that reduce time spent waiting for AI to take their turns, and all of these have found their way into a patch for all Civ V players. There are a multitude of small changes to many aspects in the game as well the trade deals got some changes, some religious abilities got modified and some technologies got shifted in order to better balance the game. People without G&K will not have access to the civilizations and scenarios from the previous expansion though. The Trialīrave New World not only includes its own new features, but also all the mechanics that Gods & Kings introduced. Now is the time to see how well Civilization V’s swan song is. The previous expansion, Gods & Kings, already revamped gameplay mechanics and added more things to the early game, whilst Brave New World adds more general changes that aim to improve the late game.
Do not expect to see any “Soma” outside achievements though, as the expansion is more about the time in which the novel was written – the industrialisation and the start of the modern era. O Brave New World that has such people in it, the last expansion for Civilization V borrows its title from the famous dystopian novel by Aldous Huxley.
