Domination setting should give you victory when you eliminated all of the enemy cities. To have them no longer listed in the diplomacy menu, showing all their cities are gone now, but they still in the game because they have worker units moving about the ocean somewhere, is ridiculous. Impossible to find them all.
Ability to select what worker units on automation can and can not do.
And all the other things I mentioned elsewhere already. Bah. Raining too hard now, so got to turn off my computer, since lightning kills computers when you live atop a hill.
