I dream of a sequel that focuses on the consequences of the legion falling apart after the second battle of hoover dam.
Basically a game where one faction wants to turn the remnants of the legion into a unified democratic republic (perhaps a mixture of the Roman senate and the NCR), another faction wants to find a new caesar (and possibly reform some of the stupider sides of the old legion) and a third faction just wants to go back to being a bunch of independent tribes that only trade with each other.
You would play as the grown up child of a legionaire who died at hoover dam and a slave who was sold off to somewhere else when you were young.
Here in Sweden we just don't use Sir/Madam at all. Everyone refers to each other by their first name, even in professional settings.
