Nice summary, Ming! Almost all know cheats were included, and the whole essay was very
neat. Good job.
In multiplayer, besides gaining moving points by trading units, and instant cash/science from trading caravans, some other things can be done to gain advantage.
a) a city can be traded between two players, and its shield production and income will be
counted twice each turn. For example, player A has a city which produces 5 shields each
turn. He passes the city to player B before B's turn, then on B's turn he gets the city back. This way he has 10 (adjusted by different waste rates of A and B) shields accrued on his next turn. And if the city has a net tax/science of 5, both A and B can get 5 tax/science (depending on their tax rates, deducting corruptions) for the turn. Considering a 3-player alliance where all cities (except capitals) were shared, the productivity can be tripled.
b) giving cities away can boost caravan trade revenue. Before giving a caravan away, ask
your partner to give some cities to you so that the caravan can be assigned to a good city. After giving out the caravan you can give the cities back.
c) Free partisans. After guerilla warfare, cancel alliance with your partner and let him occupy one of your big cities. You gain free NONE vet(?) partisans. In a 3-player alliance this can be repeated indefinitely.
Of course the above actions have drawbacks. Giving cities away destroys temples,
courthouses, and cathedrals. Also units supported by the city but not in it will be disbanded. Half of the city improvements will be destroyed when a city is occupied.
