Not that I play any games of yours, but since you want some comments
A) yes, its useful to get that information without connecting to the server.
B) no, I like A better since it is less confusing :X
C) yes, also nice (though seems to me like a superior substitute for A)
D) yes, cool for games with graphs turned on.
E) yes, if you can look at the map before joining you can avoid games of a style you won't like.
F) no, not really interesting. You could occasionally publish it for the sake of a few people's common knowledge, but sounds like work for no reason to me.
G) no, yikes!
However, after reading G I'm wondering, can one of these files show stuff like dominion/scales in every province? (and how/where?)
I was thinking of perhaps making some app that will alter a map every turn according to stuff like dominion and scales and perhaps other things, but was unable to find an easy way to reach the information needed for that. (I tried the -d switch and wandering around the log searching for relevant information but was unable to do so :X)
