In pragmatic terms it does. I love that every new version of Civ adds more official Civs
(official as opposed to mods) which does allow for more places of the world to be represented in game. But The current limit sits somewhere around 40-50. That means that if you add three random cultures, you have to drop 3 others. Hell, with Scotland, Brazil, Australia, Canada, Gran Columbia and Gaul there is some room for that; but nowhere near as much as people pushing for diversity at any cost would want.
I often make the comparison to Sports games. Your Fifa '20 game probably does have all the international teams, along with a few different leagues present in it; but imagine they only had the budget to include 50 different teams. Would you want them to include minnow's of the game like the New Zealand All Whites (
who I might add, didn't lose a game at the last world cup finals they played in...we didn't win one either, but that's another story 
) or should they include all the titans of world football first? As a New Zealander I'm not big on football; but were I, I'd want to see all the great teams I admire, and the others who give them a run for the money, before seeing my own humble nation make an appearance.
Come back to us at Civilization XX, when there's 200 Civs in game
