Sounds just great!!!
I know only too well about gamers attitude about their favorite game
Sometimes "fans" pressure can be a very destructive force. Especially if they really don`t like a change. Let`s hope Civilization fans are wiser...
For instance, I liked Heroes IV very much the moment it was out, exactly because it changed several peculiar elements from the early Heroes games. But of course the HMM fans hated the change, so after 3DO closed, the new Heroes games reverted to HMM3`s system... I never played those, and I still play sometimes HMM4
I was afraid that the card system is random... So it`s more like the ideology / religion system from Civ V: you have more option to chose from. The limit is about the number of policies in use for each government type.
More, if there are ways to change the attitude of other rulers during a campaign, even better. I just remembered the grumpy Augustus from Civ V, who was always against you no matter what...
I really like changes in a game series if these bring new challenges. For instance, I liked the option to barter with technologies from the early Civ games. I would welcome this to be back, but not angry if it doesn`t. Also, smarter barbarians are just perfect to me. I learned fast how to use them to my advantage in Civ V (and I am not talking about Bismark), but a more dangerous world in ancient / classical era is what I was expecting to be.
I`m not an historian, but history is one of my big hobbies (I have read hundreds of history books and treaties). This is the reason why I like medieval RPG`s and strategy games like Civilization. There is a book I read recently, "Sapiens - A Brief History of Humankind" by Yuval Noah Harari. Quite good. It deals more with the mental and technological revolutions. A close fit for Civilization fans.
And something completely out of topic: I found a very nice and old movie for kids (a fairy tale rock opera). It`s called Mama, and it`s a Romanian / Russian / French movie. The English version was dubbed in UK. It`s a cult movie here, in Russia and in other European countries.https://www.youtube.com/watch?v=x4Typ2fVffI
