It would be a nice touch. Although I would also like the ‘Choose biome’ system that AOE-4 has, where you choose the type of environment and ecosystem, and also choose the type of relief.
It would be nice to be able to configure in custom games:
The size of the map.
The amount of game, trees and mines.
The population limit (Up to 300).

The number of natives available, and the type of natives.
The number of trade routes and trading posts.
The amount of treasures.
It would also be good if they added game modes that have never been official:
Lost. (You start alone with the explorer on a strange and giant map and you must collect treasures in order to build the urban center.
The game mode ‘colosseum’
