I like the art style, I'll have to see about the leaders.
Gwendolyn Christie is a really good choice for the narrator.
I don't like the sound of there only being three ages, but maybe there's more to it.
Also not sure about switching civs mid-game, but being able to do things like a French Cleopatra might be fun.
Are they going to restrict this to avoid potentially offensive combos, especially in multiplayer? I'm thinking of things like using real-world colonizers for leaders of places they occupied (like an English ruler in charge of India and stuff like that.) At the very least it seems like they're inviting trouble unnecessarily.
The prices are completely bonkers, nearly $170 CAD for the Founders Edition! This is gonna be the first Civ game in a long time that I don't pick up on launch day.
