I know this is really a stupid question, but I have a game (on a world map made by me), and except a city on a one tile island (I will conquer it with marines) and a city in an island somewhere at the north of Australia I conquered every single city in the world. I just finished a war with the English (England and Persia are the only civs in the world, each of them has 1 city), a war which gave me control of South America, I made peace, loaded 3 Cavs in a Galleon which is going to get to Norwick in 10 turns. So in 11 turns I'll wipe the English and when I'll discover Amphibious War I'll wipe the Persians.
My problem is that after making peace, exactly the next turn I saw a message: "You Win! You achieved a Domination Victory.". The problem is that I wanted to conquer that 2 cities and achieve a Conquest Victory, but I won the game.
1st question: Why I won now by Domination while I had 60% of the land mass several centuries before?
2nd question: To achieve a Conquest Victory I need to continue the game I already won?
