For the people who seem to be confused as to what's different about diplo: You can't see modifiers. We don't know what's pissing them off, what's making them happy. Maybe it's the same for you if you played on Noble or Prince, but if you were on Immortal or Deity in CivIV, then playing dip carefully was a major facet of the game. As it is right now, even if you can guess whether a civ is pissed at YOU (which is somewhat possible), you can't tell whether they like/dislike other civs (beyond the occasional request for a treaty or a DOW). That makes it impossible to pick your allies carefully, to pit them against each other, to know who you have to avoid at all costs, etc. It's just a crapshoot at the moment. Instead of making strategic decisions in the diplomatic game, you have to make educated guesses. Not to mention, even if you figure out if a Civ is pissed at you/likes you, there's no real way to know to what extent. That will eventually come out when people dig through the code, but it should be somewhat available within the in-game UI.
