I'm just a casual player and I don't plan on perfecting my gameplay or anything like that but I was wondering how big of a role Behemoths, their techs and their upgrades play if you'd try to play this game well.

Like how many Behemoths would you usually make in a game? Zero? One? Five? Fifteen? And for what purposes? Economic, Science and Military?

Also do you build Obliterators, Juggernauts and Citadels? How many? Which ones do you think are better?
