OK, I'm a bit dense here and thanks for your patience but I didn't completly understand your answer.
Does this mean:
1 - I have to save my game at the end of every turn and if I want to watch a replay of that turn I have to load that individual saved game and watch only that 1 turn.
2 - You can load a saved game and watch all the previous turns in that particular saved game.
3 - Something else.
If #1 thanks. OK I understand now.
If #2 please explain how I do that.
If #3 please clarify.
Thanks
