But who cares of leaders that have a couple sentences of vocabulary and are above all and at best all annoying bastards ? I don't want to see their ugly faces when I'm trying out to figure how to win. So there's left the fact that they represent a starting choice and that you can incarnate them. And we don't even have that feeling of incarnating them when we are in front of the map. That's the problem.
You're totally wrong, the most visible aspect of the game is the map. It's the true hero of that series. That's why we should take great care of it with for example things I suggested before. The most memorable aspects of my games are when there is a civ or a city state in an awkwardly important place ; that happened only once to me. (in Civ5)
Yeah they are good to advertise the game but that's not the game itself. People are attaching importance to leaders because they can eventually incarnate them, again. And because of youtube/forums jokes hype train. That doesn't make the game itself better, it's even the contrary.
My examples are there to proove that what we think is eternal is not. All else what I said is to minimize the importance of leaderheads, according to my opinion obviously, and the vision I have of such a game that have immense potential than what it already is. If you expect more leaders, why not play Civ3, Civ4, Civ5, Civ6, or even Civ1 and Civ2 ? Do you have wet dreams as to a particular civ could be in the next iteration ? Is all this all about it for you ? I bet even not. So you see, leader heads are not the most important thing in Civ.
