Harrier, I haven't heard of anything that isn't 'upgradeable' in saves from one patch version to another, perhaps you can tell us what will still use the old rules??
No offense is take. You are right to question any statement about the game that is made by someone who does not work for the companies producing the game.
I read a post (I think it was from Tavis, but am not 100% sure and can not recall were I read it - it was a couple of weeks ago.) that said the optimum city number was taken from the saved game. Therefore the new changes to the corruption model that effected OCN (now modified ingame) would not take full effect in an old game.
As to whether a patch effects all games or not - it depends on what is changed. If it is a change to an .exe (program file) that should work. If it is the addition or removal of new units (graphic files etc) or some inbuilt parameter stored in a save game (i.e. OCN), they would not take full effect until a new game was started.
The new effects of the Forbidden palace for instance are hard coded in the .exe files - so installing the patch and loading a save game will show an effect on the next turn (when every thing is recalculated). BUt as I said in the previous post not all changes may show up if playing an old game. Why? Because we do not know what they have changed.
In mods for instance if new units/improvements are added you will not see them until you start a new game, as others have just stated.
Worst still is if a unit/improvement is removed from a mod and you install the latest version and then try to continue an old saved game it will crash. On loading your save game you get an error mesage saying it can not find a particulat file.
I was only using my experience with mod testing and a vague recollection of what I had read somewhere as the basis of my post.
As stated at the start - no offense is taken.
