Finally, some news at last. I wish we did not have to find out through leaks but at this point who cares, firaxis is quite bad at communicating with the community and keeping it engaged. This aside, from the new water based improvements we can see in the picture I'd assume water tiles and ocean tiles will become more relevant and useful compared to now. The art work of the woman looks to be in medieval clothes to me but who knows what that is. The rest we will have to see, I hope we get more units and war related features along with decent diplomacy.
