Can you make Eras for example bronze age would be he start of empires and middle ages would be age of war or reinassance the age of technology like effects to the game for tech gets advance faster one age or just war for one age time milliuiem
I'm not quite sure I get it, what effect do you suggest that those eras would have? Would they be global for the entire galaxy so that all empires are in the same era at any given time?
