Which is why ...
I'm currently considering subtracting gifted ships from your counter or disabling unit gifting altogether.
I think a 200 Naval XP goal would be easier to implement.
I also think we shouldn't disable unit gifting. I routinely gift stacks to my vassals and then give them "Why don't you attack... " orders. I find it rather effective. And realistic, especially while playing as America.
Also, there is the gifting of nukes.




Which is one of the best features of Civ IV and should not be ever disabled, IMO. Basically, my favorite way to win a Diplo victory is:
(1) Get to Friendly + Defensive Pact with the strongest civ who is not your vassal (usually for me this is England, so from here on I will refer to it as England);
(2) Instigate World War (multiple times if need be, just get England to be Furious at your enemies);
(3) Gift 20 Nukes to England;
(4) England nukes your enemies for you, getting all the diplomatic

of "You nuked us/our friend!";
(5) Propose Diplo victory in UN, run against England;
(6) Nobody votes for England because of all the nuking. Your enemies get little to no votes because England nuked them into oblivion. You win Diplo.
(7) Send a message of thanks to the English leader.
