I'm not entirely convince BNW is ready for prime time, and I was much more impressed and infatuated with Gods and Kings. It seems like the AI is slightly off kilter and the new sides seem heavily unbalanced. Tourism is just kind of "out there", feeling really detatched from any of the other mechanics, and the game seems to drag at points. However, with all this said I must admit what this expansiom gets right, it gets right hard. The new side selection all seem perfectly worthy of inclusion, the new trade mechanisms, while agravating at times, add much to diplomacy and the friendhip/ denounce system, and the happiness rebalance is both very noticable and VERY appreciated. I'm still happy with my purchase, but I will be happier a few patches down the road.
