I haven't watched Rome, but that didn't stop my absolute enjoyment of this fanfic. It's not just that Joffrey is replaced by someone who isn't insane and narcissistic, it's that he's replaced by someone who is both supremely competent and from a similar social, political and military milieu. So you have a character that doesn't even blink at the Jaime/Cersei incest and has a practical understanding of what is required for world conquest.
