We have an option in the game setting to have only antiquity or medieval civilization or both. Good don’t change this.
But if a in group of players one of them want to play only medieval civilization and the other want to play only antiquity civilization. They can but the time to choose a civilization is very long :
The player who want to play only medieval civilization must make a custom group and must click 45 time for all the medieval civilizations. And in the future the number of medieval civilization will certainly increase and he must click more.
The player who want to play only antiquity civilization must make a custom group and must click 3 time for all the medieval civilizations. And in the future the number of antiquity civilization will certainly increase and he must click more.
We can make of group to pick the civilization than we want but I propose two new options
Random Chronicles civilization You pick a random antiquity civilization
Random Age of Empires 2 civilization You pick a random medieval civilization
