Thanks for kindly explaining it e Mare, however I was just curious because what if a majority of people don't want a certain person in it?
That can only work at the start of a game.
At later stages, when factions have usually formed, some people want others out of the game, e.g., when they would inevitably lose but naturally don't want that to happen, so they would decide to kick the player( against whom the 2 players have ganged up)
Even if this is only used at the start of a game, kicking players where this would work - scenarios with a lot of players( ensuring a fair vote) or whole whole world games - would in turn be bad for the game itself, specially in the former case the game has players distributed all over the map, allowing them to control specific areas.
This also balances the game and may also fulfill the role of historical accuracy, which is what many people enjoy.
E.g., Germany getting kicked out of a WWII means what the game is about doesn't happen - World War.
