+1.
And I'd add Civ V leaderscreens back, too. I want to talk with leaders on horses, thrones, in their gardens, palaces, and so on, not just some black room with a banner.
And more leader lines, too. I'm tired of leaders that have only six lines (and some grunts), and they're mute for the rest of the game.
And since I can't decide if I like era-themes or peace/war themes more, I think that's all.
