Lifelong Civ player. I have always felt the negotiations part of the game is laughably bad, and a huge missed opportunity. The ability to use language as a tool -- diplomacy, but also rhetoric, veiled threats, etc -- is something I excel at, and I would love the chance to test my mettle against an enemy in an imaginary nuclear war context, because when else do you get to play high stakes games like that with words in real life? Civ is the perfect venue for it, but the game designers are extremely boneheaded about how they executed that particular part of the game.
