I have read some mentions that it will be possible to play with all the nations from all the three ages, IIRC this should be possible via an "anachronistic mod".
I was wondering if that mod is ready or not and also whether the balance between nations of different ages in such mod was considered or, better yet, tested.
From what I gather there are considerable changes between nations in different ages, so just technically allowing to choose every nation might not be sufficient if the nations are significantly unbalanced across ages.
Given the wealth of nations in all ages I think it will be really nice if the option the play all the nations will be viable.
( Also such an option will make it possible to determine which nation rules
)
