In future do you plan to have civs in mod only from WWI or it will be combination from WWI and colony era civs?
I ask you this because I think that you now in colony era have some civs with heroes or units from WWI (or near to WWI). It is not interesting that you play with civ which have colony era units vs civ which have WWI era units.
It would be great to made two versions of mod one WWI era civs and the second with colony era civs.
If you plan to build only WWI era units/heroes than what would be with Haiti, Mexico, Zulu, Sioux and other interesting civs?
