It would be nice if you could add a Post Imperial age game start. Meaning that the game starts in Imperial age with all technologies researched.
Also Post Castle age starts, where the game starts in castle with all techs up to castle age researched.
This feature was there previously in AoE3 and possibly AoE2 and its nice for casual games where you just build armies and battle it out without worrying about researching techs.
And hopefully you’ll add treaty mode as well with 10, 20, 30, 40 and 60 minute treaties.
