IMO, dividing up the special edition units in that way will only encourage people to download them, or very close variations of them made by modders, rather than get the specific versions. Since it's impossible to get all of them legitimately without 1) Buying all of the various editions (which would cost about $200) and 2) Modding the game to let you use all the various units somehow from all the installations.


As to Cossacks, I do hope they'd be a standard unit for Russia. And hopefully not just a standard 'Cossacks' unit. There's way too much variation among the different tribes to leave them as just plain ol' Cossacks.
