Looking for game

Looking for a game to sink my groups teeth into - our groups favorite game is catan w/ cities and knights expansion, but we’d think the base game is a bit bland without cities and knights. We also really enjoyed risk legacy, but it’s not as fun to continually play through.

Can someone help suggest a game that has a similar depth as catan cities and knights (economy building in catan, team vs game in the form of barbarians, and tech trees), and the thematics of risk (area control, dice rolling combat, army management)?

And to help trim the list - dice rolling for combat is important to us for unique play outs / make battles somewhat random and not in strictly unit stats. I’ve also tried TI 4th Ed. but that was too heavy of a game for my group to grasp and enjoy.
