You can read about the cultures here if you don't remember them. If you can, please explain your choice because I think many people are interested to know why you choose that culture as your favorit ancient era one.

I picked the Hittites I know a lot of players feel they are on the weaker side, especially if compared to the Myceneans, but they are a nice defensive civ with the +1 combat strength and the Awari and in this scenario where the AI seemed to be so aggressive they were very useful to me to eliminate green early on with my +1 combat strength scouts (I know Harappans would be better for that purpose but I couldn't manage to pick them before the AI).
