The Civ-series in general, and Civ 6 in particular, is very "big tent". You can see in the comments on this forum how often people assume that most people play Civ for the same reasons they play Civ, but in reality, I'm not sure any particular player-type makes up a significant % of the overall Civ audience, let alone a majority of the overall Civ audience. I've no doubt that there are lots of people who enjoy Civ and the Europa series both, but I expect the overlap would still be a small % of the overall Civ playerbase. Same thing for Old World, Sim City, Risk and Candy Crush.
