Spoiler for Boring text from before I started writing the real thing:
So, to start off, I've never written an AAR before, but read a lot of them so far; and the only thing from stopping me write my own was that I never had anything interesting to write about.
And now, far off into my campaign which I'm meaning to use for my AAR, I think I got an interesting battle in front of me, and was wondering if it's permitted to write an AAR about a certain part in a campaign rather than from the beginning of the same?
If it is, you can expect the first part, 'Introduction', in the coming days.
