Like in the previous games in the series, each of the 18 civilizations receives unique units, buildings and traits to give it special abilities during the game. However for Civ V, we’ve worked hard to ensure that these bonuses dramatically shift your experience while playing the game. There is a world of difference between playing India (who has bonuses to create an empire of few, heavily-populated cities) and playing Russia (who is very good at spreading out over the entire map and claiming resource sites, despite having a low population density). My own favorite is the Ottoman Empire who recruits barbarian naval units to their side and can then use them to terrorize the coastlines of other players. And trying out all these unique play styles to figure out your own personal favorite is a large part of the fun.
