Age of Mythology
I hear some of the developers of Age of Mythology are at Robot Entertainment.
This was honestly one of my favorite RTS games of all time. I personally found it more fun than AoE3.
God powers, choosing a God to follow at each age, and the extremely unique elements of each race, were some of my favorite features. All of these things made your choices feel very impactful and meaningful. Most RTS games don't have a concept of "pick this OR this (not both)", which I find to be an extremely fun decision.
If you worked on AoM, I'd love to talk to you.
Either way, I hope someday to see an AoM 2.
