What if? Justinan only focus on taking city of Rome.
Instead of spreading his campaign or reuniting the roman empire, and trying to take back almost every land available in his lifetime, Justinan only focus on taking the city of rome and other nearby cities?
Which means he is ignoring other parts of Italy first, and once he take Rome, he tried to fortify it and build massive defense and so on.
Will the consequences of such actions ensured that first, the real roman empire will be viewed as the real or true roman empire all the way into the middle ages by every european and so on, and most importantly, ensure that the eastern empire will not be bankrupted?
