Interview at PCGamer, quite a good read:

"One good example of that is that, in my mind, there are two kinds of Civilization games. There's Civilization 4 and Civilization 5, then there's Civ Rev. Civ Rev is my favourite, it's the last Civ that Sid Meier himself has designed, that's in the Civ canon. It's a much more asymmetrically balanced game, whereas Civ 4 and 5 where symmetrically balanced games. There's a lot more drama in Civ Rev, for me as a player. The game can swing very dramatically one way or the other, and that's been an issue, resolving the desire to get that sort of drama in the game, while at the same time not upsetting fans of Civ V too much. There are different voices in our office for each of those perspectives."
I certainly hope it won't be to much Civ Rev'ish.
