I was inspired by some Age of Empires gametypes, like Regicide, and Capture the Hill in AoM. What type of gametypes would you like to see besides standard ones?

I think they should have an official City Builder type where war can only be allowed if it is announced or if someone crosses your border, and then it takes 30 seconds before you can attack. Or the only attacking can be done on he center planet.

Ideas? Criticisms? I know this place is practically dead so there's little use posting here but hey, I try right?
