How does diplomacy in Multiplayer take place?
The one major different in Multiplayer diplomacy is that you cannot see what the other human has (but you can for AIs). Other than that, diplomacy in the ‘real time’ modes, Internet and LAN, are just like normal Civilization where you can each put things on your side of the bargaining table. However, in PBEM and Hotseat, it uses a method that can sometimes take a couple turns to complete – the side that engages diplomacy can first offer something on their side of the table, and then they ‘send’ the deal to the other civilization. When they play their turn, they’ll get the updated trade table, where they can add stuff to their side and change what is being negotiated. Then, when each side has agreed on the deal, both must click the “Agree” button in order for the trade to become reality!
