Waiting on Russia, but I'm currently going between France, Spain, and Arabia. I feel each of them have unique things that would lend themselves to certain victory types that I want to try out (Culture/Military, Religious/Military, Religious/Military/Science, respectively). Also England to really play with the new continents system. Here's hoping Russia has something off the wall that screams first game to me---they were my first civ in Civ5 and I might want to start a tradition Peter presents a lot of possibilities, but I'm hoping that his emphasis on Westernization (while questionable) plays into the new continent system and doesn't hinge on being technologically behind other civs. In general, I feel those types of UAs really prove useless to higher level civs.
