Am I imagining things or is the AI much less aggressive towards the player in BNW? I'm finishing up my 6th epic-speed game in BNW with 6 different civs on either Emperor or Immortal difficulty and I have not had a single AI civ declare war on me in any of those 6 games. I've engaged in a couple wars but only because I declared them myself. In some of the games I went the entire game without engaging in a single military action.
I don't remember a single pre-BNW game where I didn't have an AI civ at least threaten to declare war on me if I didn't pay them not to.
