It's funny, I looked at it again the other day and realised it's not actually that bad value. You get 6 city-states, 2 of which come offering their own unique Improvement. 3 Natural Wonders. And then a scenario. Compare this to the Poland DLC, which had 1 civ with a Unique Unit and Building, and scenario. It's actually pretty balanced in terms of content. Nevertheless, I understand why people were disappointed. Civs and leaders are definitely the priority among most players.
