If you could include new mechanics, features or functions in AOE-3, what would you implement?

[OperaticShip743]

Imperial cards. Age 5 is the only age that is not covered by this function. They would be very useful for the treated mode.

Imperial Cards Suggestion

It would be nice to see Imperial cards created. I think that for Ages 1-4 you would still stick to the 25 out of 25 cards but Imperial cards would not be considered part of the 25 out of 25 and instead would have their own limit 5 out of 5 (or whatever amount seems fair). Thoughts?
