Plus, there will always be modders to add the "best" leaders everyone complains about being missingToo many people see the Civilization series as some sort of award ceremony for recognising history’s “worthiest” cultures and leaders according to some painfully conventional criteria that favours warmongering and received wisdom.
I’m definitely in the camp that favours the inclusion of some lesser known and “interesting” leaders, and I enjoy the approach Firaxis have taken with Civ 6 immensely. Kristina and Ludwig are inspired choices, even if they irk some people.
And I say this as someone from a country that will only ever have the same three leaders recycled again and again and again… (prove me wrong in Civ 7, Firaxis!)
Abraham Lincoln and Julius Caesar already had mods adding them to the game before Firaxis did themselves.
As for Louis, I personally don't know much about him. But based on his intro text (which is phenomenal), I certainly get the feeling this is a personality big enough to warrant Civ VI's criteria,
