Eh, I don't have an excuse, I've been playing since launch day. I *should* have at least one base as badass as your own, but I am far too casual a player for the number of alts I try to support (over 30, I think).
Hell, my main Security has the top floor of his base dedicated as his "Krypton room" and even that isn't on the same level as your entire Fortress base!
