Jesus rollerblading Christ, this expansion will be so glorious.
I love the new map and all these new options.
Mesoamerica and South America went from 4 nations and one joke into, if I remember correctly, THIRTY SEVEN nations
West Africa has like 3x more countries
Epic land connections between West Africa, East Africa and Tripoli while deleting idiotic Spanish colonization in Mauretania will improve Africa soo much
New countries in the Eastern Africa (was it Makuria south from Mamluks?)
A lot of new provinces in Persia and India, finally expanded Caucasus
Greatly improved South-East Asia with many new provinces, division of Indonesia
A lot of new provinces in China and Korea, Manchu Hordes, new mechanisms
And my biggest shock: SIBERIAN NATONS. I am not talking about Mongol Hordes but about Kamchatka (!) and few other nations in Eastern Siberia (!!). Not sure if it is 100% realistic they are organised states but it is surely awesome.
Also, garrisons can now SORTIE. Devs didn't say anything about that, but we have seen 'sortie' garrison button and it is enough for me to be excited - so many new tactical options... And finally the ability to get rid of pointless 1 - 2k 'sieges'.
Personally I also love changes to the Rebels system - I am 'fan' of rebels as they introduce a lot of fascinating dynamism to the game, and in AOW they will be reorganised, more interesting and stronger...
Now when I love new map, there is one area I would like to see - Central and South Africa. I am pretty sure areas of Kongo, Lake Victoria and Mutapa could be improved.
