First off, I'm no modder. So there is probably a better way to do this, and if someone knows it, please advise.
Anyway, I get tired of setting the options at the start of a scenario from the default to those that I like to play with, so I looked around in the scenario files and found a section in each called [OPTIONS]
Having set the options ingame to what I generally want, I saved and then copied the resulting [OPTIONS] section of the save game file to a template.txt.
Then I can one time go into the various scenario files and overwrite the default options with those in the template.
No, it's not elegant, but perhaps useful to some of you.

By the way, I don't see any entries for fog of war, so have no idea how those choices are saved.
