Sid Meier's Civilization V: Brave New World is the second expansion pack to Civilization V that actually improves gameplay dynamics and enhances the true experience of what Civilization should have been. Brave New World radically change the cultural system, adding Great Arts and Great Works to promote tourism to the establishment of the World Congress for advanced diplomacy. Civilization V with the first expansion pack, Gods & Kings, was already considered as the "cocaine" of video games, but with Brave New World, this makes a lethal addiction to the level of meth (just an inside joke among Civilization players since the series is highly addicting). Additional buildings and units are added to truly connect to each eras from Medieval to Atomic Era to experience what it's like. I cannot express how grateful this expansion pack brought Civilization V as the highest standpoint in any video game. I strongly recommend to current Civilization V players to get this expansion at ANY price (ranging from the steep discount to the default price of $30). Firaxis Games has once again truly represent their community with great positivity and I will support this company to the last day and one more.
